Pneumatic Butterfly Valves

Butterfly valve is typically used for the regulation of fluid flow. It is most widely used for supply of water for fire protection, for industries related to fuel and chemical along with various other applications. Unlike the ball valves, butterfly valves actually operate with single quarter-turn mechanism. There are various types of butterfly valves which can be found in the market today.

Butterfly valve is basically based on the principle of quick shut off. It functions with a disc in the center pipe which permits a small rod to pass through it to the actuator which is present on the external side of the valve. The valve allows the flow of fluid when the user rotates the disc with a quarter turn. It is also known as the quarter-turn valve. The valve gets its name from the metal disc attached to the rod which helps in permitting the flow of fluid with a quarter turn and also helps in blocking the passage. This disc, which is often called as the butterfly is the most part of this form of valve.

The best butterfly valve that you can use depends on your purpose of using the valve. It has gained quick popularity in the industry due to its easy to start, stop and regulating feature.

You can get four different types of butterfly valves in the market.

  • Motorized Butterfly Valve:   

    This type of valve is used widely for controlling the flow of fluid via a pipeline. It operates by simply altering the position of the round disc which is present with a system pipeline. You can use this type of valve for pipeline o any size as they are available in various sizes and specifications which you can choose according to your need.

  • Concentric Butterfly Valve:

    This type of valve is used for the regulation of low-pressure pipelines. This can be installed very easily and will also provide with the 100% efficiency. This type of valve is the lightest of all.

  • Wafer-Type Butterfly Valve:

    It is very easy to use type of valve but it fails to function as the valve for isolation.

  • Pre-insulated Butterfly Valve:

    This type of valve is the most durable out of all and are resistant to cracks.

Ball valves- Uses in food & beverage industry

Ball Valve is the valve that can either be turned on or off by opening the valve and closing the valve, respectively. This type of valve uses a hollow, perforated, and pivoting ball to control flow through it. If the handle of the ball valves lies flat in alignment with the flow, then the valve is in an open state. When the handle of the valve is perpendicular, then the ball valve is closed. Hence the confirmation of the ball valve status can be checked easily by looking at the alignment of the ball valve handle. 

Whenever we are going to any online grocery stores and purchase food items likes cereals, cookies, canned fruits, and pastries, you might have wondered how this food must have been processed. This is where ball valves play a crucial role in the food and beverage industries.  Ball valves are flow valves that are quarter turn is used to shut off and control purposes. The ball valves are very easy to operate and can control and maintain high volume, high flow of temperature, and high pressure.

 Ball valves are more efficient than traditional butterfly valves that are explicitly used for the circulation of stream water only. Ball valves that are used in food processing industries can be subclassified into two categories. They can be a valve that comes in direct contact with the food and the second that are used in utility services involved in the food industry.

Both of these types of Ball valve are regulated, but the one which is in direct contact of food must undergo stringent checks. Even a small contaminant in the valve will lead to compromise with product quality and increase the cost of production.

 

Types of Ball valves that are used in Food and beverage industries

  • One-piece Ball Valves:- These types of ball valves are less in cost and are basically “throw-away” type valve. There are no leakage points in this category of ball valves.
  • Two-piece ball valves:- These types of ball valves are most common. It has one body joint that has fewer chances of leaks. They can take part in maintenance as well.
  • Three-piece ball valves:-These types of ball valves can be disassembled easily for maintenance. The internal parts can easily be swapped.

Pressure Reducing Valves in Hydraulic system

Valves are considered to be the essential components in the hydraulic system. A valve that maintains lower pressures in the hydraulic system is called a pressure-reducing valve. Valves are considered to be the crucial components in the hydraulic system. A valve that maintains lower pressures in the hydraulic system is called a pressure-reducing valve. It determines the upstream main system pressures. A pressure-reducing valve is an open, two-way valve that allows system pressure fluid to flow it until a set pressure is achieved downstream. Pressure reducing valves then shifts to throttle flow into the branch. SKG Pneumatics is the best pneumatic company that is the largest suppliers of industrial valves in Delhi.

Basic components of Pressure reducing valves

The main components of pressure reducing valves include Adjusting screw, Adjusting spring, Diaphragm, Inlet port, Valve Disk, Valve stem and Outlet port.

Difference between pressure safety valve and pressure relief valve

Sometimes people confuse with similar terms pressure safety valves and pressure relief valves. Even though pressure safety valve or pressure relief valve sounds identical but they are different altogether. The difference is that pressure safety valves have a manual lever to activate the valve in case of emergency. However, most Pressure relief valves are spring operated.

Hydraulic pressure control using Pressure release valve

The pressure at which the valve begins to open is called crackling pressure of the valve. However, the pressure at which the relief valve is completely open is full flow pressure. The difference between the crackling pressure and flow pressure is called pressure override.

There is always a risk to life, property and environment while using a hydraulic system. That is why the safety relief valve is required to protect the hydraulic system against overpressure so that the system does not fail.

Classification of the safety relief valve

A type of valve which opens and closes through valve disc due to increase and decrease of pressure, thereby controlling the discharge is called safety valve. They are classified into

  • Low Lift Safety Relief Valve
  • Full Lift Safety Relief Valve
  • Full Bore Safety Relief Valve

SKG Pneumatics is the leading pressure control valve suppliers in India. The company manufactures different types of valves that are used for several purposes. It is also the largest suppliers of industrial valves in Delhi. The company has been manufacturing valves of various types for decades. The company has its office in New Delhi, but it supplies valves in all states of India.

Hydraulic Valves – Types and Components

A mechanical device that controls the flow of the liquid, usually by opening and closing is referred to as a valve. The primary purpose of a hydraulic valve is to direct the flow of a liquid medium that will move actuators and loads through the hydraulic system. There are various types of hydraulic valves and it is important to choose the right one to get the best results. 

What are the different types of hydraulic valves?

Hydraulic valves come in a variety of sizes and with different mounting styles. There are three major categories of hydraulic valves namely directional control valves, pressure control valves and flow control valves. 

Directional Control Valves

The primary purpose of a directional control valve is to control the direction of the fluid flow. The three functions performed by directional control valves include stopping the fluid flow, allowing the fluid flow, and changing the direction of the fluid flow. 

There are five types of directional control valves:

  • Check valves
  • Shuttle valves
  • Two-way valves
  • Threeway valves
  • Fourway valves

Pressure Control Valves

A pressure control valve helps in maintaining a set pressure in the hydraulic system. Pressure control valves are used mainly in industries where keeping system pressure below a desired upper limit is crucial such as oil and gas industries. 

There are types of pressure control valves:

  • Relief valves
  • Constant pressure reducing valves
  • Sequence valves
  • Counterbalance valves
  • Over center valves
  • Unloading valves

Flow Control Valves

Flow control valves regulate the flow rate at the throttling point by increasing or decreasing the opening of a hydraulic circuit. The flow rate helps in determining the rate of energy transfer at any given pressure. 

There are five most common types of flow control valves:

Heating, Ventilation, and Air Conditioning System (HVAC)


Since all the mechanical systems that provide thermal comfort and air quality in a room/indoor area are interconnected, they are often grouped together and are called HVAC systems. It includes central air conditioners, heat pumps, boilers, furnaces, rooftop units, chillers, and packaged units.

HVAC valves are used to control flow in pipes. Major components of an HVAC system such as water chiller, cooling water pumps, air handling units, and fan coil units use valves to control the flow of water, gas, and air.

What is HVAC System?

HVAC is the acronym for Heating, Ventilation, and Air Conditioning. HVAC refers to the various systems that are used along with heating and cooling buildings (both commercial and residential). An HVAC system is responsible for keeping you fresh and cool in summer and making you feel warm and cosy in winter. Apart from just keeping a place warm or cool, HVAC systems are also responsible for improving indoor air quality while providing comfort to everyone inside the building.

What are the different types of valves used in HVAC System?

Plug valves (seat valves), ball valves, and butterfly valves are the most common types of valves used in heating, ventilation, and air conditioning system. Other valves used in HVAC system include knife gate valves, diaphragm valves, and gate valves.

Heating and cooling Hydronics-triple duty valves acts as a check valve, shut-off valve, and balancing valve all at the same time. Automatic flow limiting valves are used to vary the speed pumping systems that control the flow of the water in HVAC systems while automatic temperature control valves are used to reduce the temperature of the water in the domestic hot water pipe.

A pressure reducing valve is used to reduce the pressure of the water in the HVAC hydronic loop while circuit setter valves are used to maintain a set amount of flow through a piping loop.

HVAC systems not only regulate the temperature of the indoor space but also maintain the indoor air quality. However, it is important to use high-quality industrial valves in order to get the best results.

SKG PNEUMATICS INC is the leading industrial valve suppliers in India. In fact, all their valves go through multiple ruggedness-testing procedures to ensure that their customers receive the best industrial valves.

Applications and Working process of Control Valve


A valve is a device that regulates the fluid flow as well as the pressure within a system or process. Unlike on-off valves, a control valve is used to regulate the fluid flow by stopping and starting the fluid flow as per the direction is given by the controller.

Control Valve

Control valves consist of three main parts: the valve, the actuator, and the controller. Various components of the Actuator include rain cap, eye bolt, diaphragm, spring, actuator stem, diaphragm case, scale plate, stem connector, and yoke.

The components of body part include packing flange, packing follower, yoke claim nut, gland packing, valve stem, bonnet, stud bolt and nut, gasket, guide ring, guide bushing, valve plug, seat ring, valve body, trim set, and positioner.

Though the primary purpose of a control valve is to regulate the fluid flow, there are two main forms of action i.e. the sliding stem and the rotary action. The most common type of control valves in the sliding stem include globe valve, angle body valve, and angle seat piston valve while the rotary action includes a butterfly valve and ball valve.

Why Control Valves are Used?

Control valves are used for various purposes in the industrial, engineering, manufacturing, and scientific communities. The primary purpose of a control valve is to regulate the rate of the fluid flow by varying the size of the flow passage. Control valves are most commonly used for consequential control of process quantities including pressure, temperature, and the liquid level.

How do Control Valves work?

With the help of opening and closing internal passages, control valves regulate the fluid flow. Control valves form a control loop which is then used by a controller to send signals. Control valves respond to these signals and adjust the internal openings accordingly.

Control valves use the actuator to move the valve stem. Usually, it is either air (pneumatically) or electrically driven. The pressure between the inlet and outlet decides the rate of flow through the valve.

In order to reduce the fluid flow, the valve is closed, which results in more back-pressure and increases the difference between the inlet and outlet pressures.

Control valves help in controlling the fluid flow and are used in various industries including pipeline, oil & gas, food & beverage, the biopharma industry, and marine industry.

Let’s have a look on our range in Balancing Valves

SKG PNEUMATICS INC is one of the leading trader & dealers of all kinds of industrial products. We have a complete range of balancing valves according to their size, pressure ratings, operating temperature, and fluid characters including on-site commissioning for optimum performance. 

What is Balancing Valve?

The valves that are used in the central heating and cooling systems based on the flow of the water are termed as Balancing Valves. Balancing is a practical technique for setting systems to meet design requirements. It helps overcome a wide range of system conditions where pipe sizing and pipe configurations alone cannot set a system in balance. The latest flow technology is used by these valves and they also ensure that if there is no change in the pressure within the system then the design flow rate of the system will be achieved at all times. The rate of the design flow is determined by the velocity of the water flow in the tube of the coils. The minimum flow is 1.5 ft / s (0.46 m / s) and the maximum flow is 12 ft / s (3.7 m / s).

We have a range of Balancing Valves from Advance Valves

  • Excellent track record.

Balancing Valves – Screwed

When the system is unbalanced, water takes the easiest path through the system where the resistance is lowest and as per the result of the terminal units, radiators, fan coils, air handling units, chilled beams and radiant panels that are closest to the pump are provided with excess water flow. Units that are further away from the pump, seek insufficient flow. When balancing a system, flow distribution is changed so that critical circuits can be provided with the required flow. When the system is balanced, water flow can be set to design the requirements of all parts of the circuits. This results in good thermal comfort and no unnecessary energy consumption. Screwed balancing valves are the efficient operation of control devices to achieve energy savings, Room temperatures will be optimized throughout the building and lower fuel bills for the building occupier. 

Balancing valves – Flanged

Flanged balancing valves help ensure that all components in a hydronic system achieve the required design flow. These valves are more accurate than screwed Balancing valves. The effect on the selection of the control by the flow system was not initially realized but flanged balancing valves are very effective for this purpose.

Applications of the balancing valves

There are numerous applications of the balancing valves. They are mostly used in boilers and HVAC chiller system to regulate the flow of liquids such as water. Creating a consistent output pressure to a system from an inconsistent input pressure from another system is the main purpose of the balancing valves. Balancing valves are also used as the heat exchangers for ensuring the optimum flow of the liquid throughout the system.

How does it work: Gate Valves

Gate valves are the most common valves found in the distribution system. Gate valves are mostly used for the on/ off control. Gate valves prevent the flow of the liquid in both directions. They are very easy to install and to maintain. Gate valves are cost-efficient and they are mostly used in petroleum industries because of their abilities to cut through liquids. 

What is a Gate Valve?

A gate valve is a linear motion valve that is used to start or stop the flow of the fluid in piping. There is a gate or wedge type disk which moves perpendicular to the flow which directs the flow to stop or start. In any process plant, the gate valve has the most common use and are suitable for both above-ground and underground installations. 

A gate valve is also known as a sluice valve. It is very easy to open it, one just have to lift the gate out of the path of the fluid. It does not require a wide surface; it fits in a very little space along the pipe axis. It requires a 360° surface contact between disk and seat to achieve proper sealing. A Gate valve is made up of certain parts that allow it to function properly. Valve’s body or shell is the most principle part of this particular valve which can connect the inlet and outlet pipes in a piping system. 

What are the different applications of Gate Valves?

Mainly it is used for all kinds of applications and it is the best fit for all types of above ground and underground applications.

  • It is mostly used when the pressure loss is minimum and when the free bore loss is needed.
  • It can be used for numbers of fluids and it is suitable for potable water, wastewater and neutral liquids 
  • The temperature is required between -20 and + 70-degree centigrade for which the velocity of the flow should be 5 m/s and up to 16 bar differential pressure. 

 

What is the working principle of the Gate Valve?

There is a handle wheel on the top of the gate valve and when this wheel will be rotated in a clockwise direction, the steam and gate will move in the downward direction. It prevents the leakage of fluid through the valve.

When the wheel is rotated in the anti-clockwise direction, the valve will be opened and the steam and gate will move in the upward direction across the fluid. The gate valve can also be used in the semi-opened direction but the erosion of gate as fluid will strike and hence it is not recommended to open it partially. 

 

SKG Pneumatics Inc is one of the best suppliers of all kinds of industrial valves such as Gate Valves, motorized gate valves and flanged gate valves. If you want to buy any kind of valves, then we are always at your service with our heart and soul. We are the leading suppliers of the motorized gate valves and gate valve manufacturers in India.

Valve Design and Working Principle of Butterfly Valve

A butterfly valve is used to isolate or regulate the flow of a fluid. It can be used for a wide range of applications such as water supply, wastewater treatment, and fire protection, for chemical and fuel industries and many more. 

Butterfly Valve Working Principle

It is based on the quick shut off principle. The disc of the valve is placed in the center of the pipe which allows a rod to go through it to an actuator, on the outer side of the valve. The disc remains parallel or perpendicular to the flow. A pressure drop is introduced by the disc upon the flow even when open. 

It open or closed when the disc is rotated a quarter turn and hence it is also known as a quarter-turn valve. There is a metal disc on the rod and when the valve is closed it blocks the passageway by giving it a quarter turn. This metal disc is known as a butterfly. It is the most important component of the valve. 

Butterfly valve classification

Butterfly valves are quick to open type valves used to stop, regulate and start the flow of the fluid. A gearbox type actuator is attached with large butterfly valves and a hand wheel is connected to the stem of the valve via a gearbox. The butterfly valve is classified into four types.

  • Centric Butterfly valves: Centric butterfly valves are also known as soft seated valves. They are used for low- pressure and non- critical applications in gate and ball valves. They are very cost-efficient and easy to install. Centric butterfly valves are also very lightweight.
  • Motorized butterfly valve: Motorized butterfly valves are used to control the media flowing through the pipelines of the system. By changing the position of a round disc within a pipeline, it starts operating. They are available in many different sizes and they can be fit into any type of specifications. 
  • `Pre-insulated butterfly valves: Pre-insulated butterfly valves avoid the cost as well as manpower for insulating the valve after installation. They are made up of very fine quality materials. They are of very simple design and enhance durability. Pre-insulated valves have a long service life and they are crack resistance.
  • Wafer type butterfly valve: wafer type butterfly valve is very easy to install into the system but it does not work as an isolation valve. It is placed between pipe flanges and the flange bolts encircle the valve body.

Butterfly valves design

The butterfly valve comes into two designs, centric and eccentric. The only difference between these two designs is, in centric butterfly valve stem is placed in the center of the disc and disc is placed in the center of the bore. Whereas in eccentric butterfly valves, there can be more than one stem placed offset from the center.

How Fire Sprinkler System Work?

Fire is an ultimate nightmare for those who run a store or warehouse. Just imagine your building is stocked with furniture and other flammable items and a fire breaks out at night when no one is around. No need to worry we are here with a fire- fighting system which can react the moment trouble strikes. It has a sounding alarm and an automated sprinkler system to put out a fire as quickly as possible. Fire sprinklers are not for business use only they are also worth having in homes. This is one of the best fire protection systems which have protected life and property for over 100 years.

A fire sprinkler system seems to be a simple system made up of pipes with sprinkler head that deliver water to a fire. But it is a complex system that is carefully designed, installed and tested. An automatic fire sprinkler system works when high heat triggers the sprinkler system. The air above the sprinkler heats rapidly when a flame ignites. When this hot air reaches a sprinkler’s head, it triggers a chain reaction. The sprinkler is filled with a glycerin-based liquid expands when it comes in contact with the hot air and the sprinkler head activates. A fire sprinkler system is ready to install after the designing process.

Fire system installation process is quite simple and it is done by the pipe fitters at the construction site. There is a need of commercial sprinkler system in commercial buildings as a fire could seriously injure or kill employees or customers, damage property, destroy paper records. A fire sprinkler system makes your business safer. The automatic fire sprinkler system detects the fire and it is far way better than the spray that is used to extinguish the fire.

So if you are also willing to make your business safer than automatic fire sprinkler system is the right choice for you. SKG Pneumatic Inc is the one stop destination for complete range of industrial products. We are one of the leading fire fighting equipment suppliers.
