What is Valve Automation? 

Industrial valves are mechanical devices that are used in various industries to control the flow of fluids and gases. 

Valve automation is the process of adding a valve actuator and control system to the valve and can be powered by electric, human, hydraulic, or pneumatic energy. 

Just like valves, there are different types of valve automation.  

Types of Valve Automation

  • Manual: There are various ways to use valve automation via manual energy. This includes hand wheels, levers, and gears. Since it is manually operated, it isn’t as costly as other methods. However, it is impossible to operate larger valves manually because of the high thrust requirements. There can also be a safety issue if the valve is located in remote or hazardous environments. 
  • Pneumatic: Pneumatic valve actuators use gas or air pressure as its power source to turn the valve on or off. Because of their simplistic design, they require minimal maintenance. Besides, they can be even used in areas with extreme temperatures. 
  • Hydraulic: Much like Pneumatic valve actuators, hydraulic valves use fluid pressure as its power source. Hydraulic actuators are suited for high-force applications, and they can produce more significant force than pneumatic actuators of the same size. 
  • Electric: The electric actuator converts electrical energy into torque to operate the machine. Out of the four types, electric valve actuators offer the highest precision control positioning. Besides, they are non-toxic, quiet, and energy-efficient. They are expensive and not ideal for applications that require high speed or failure modes. 

Difference between Valves & Actuators

If you have worked with industrial valve suppliers, you might know that both valves and actuators play a crucial role in automating process control. 

A valve is used to control the amount of fluid flowing through a pipe/machine. However, you must

A valve is used to control the amount of fluid flowing through a pipe/machine. However, you must set it either in a specific position or control it manually. Actuators, on the other hand, is controlled by a computer system that uses different sensors which dictate the action of the actuator and therefore the valve.

Importance of Check Valves in Hydraulic Systems


A check valve is a mechanical device that is used to prevent backflow in a piping system. In other words, check valves obstruct the fluid flow in one direction and enables unobstructed flow in the opposite direction. The check valve is also commonly known as a non-return valve (NRV) or a one-way valve. 

Check valves have two openings in the body, one for the entry of the fluid and another for an exit. Check valves are largely used in household items, however, they also serve a great purpose in controlling the direction of fluid flow in hydraulic systems. Since there are too many check valve suppliers in India, you need to find the one who provides industrial quality check valves. 

What is a Hydraulic System?

Most industries require a controlled application of force and these operations are usually carried out using electrical or fuel-based machines as a prime mover. However, specially designed enclosed fluid systems can also provide controlled motion and force to the substances. These systems are capable of providing both linear as well as rotary motion and it also allows us to apply high magnitude controlled force. This kind of enclosed fluid-based system that uses pressurized incompressible liquids as transmission media is known as a hydraulic system.

What are Hydraulic Control Valves?

A hydraulic control valve is a device that has the capability to change the opening degree of the fluid flow path. Additionally, control valves are also used to regulate the speed of the fluid flow to the motors and cylinders.

Most common Hydraulic control valves types

  • Directional control valves
  • Pressure control valves
  • Flow control valves

These hydraulic valves can be controlled by manual, mechanical, hydraulic, electric, electro-hydraulic, pneumatic, and input control, on or off fluid flow channels. 

What is the importance of check valves in Hydraulic Systems?

Check valves serve a variety of purposes in hydraulic systems. It is important because: 

  • It blocks pressure spikes
  • Prevents oil lines from draining
  • Blocks oil flow from the accumulator
  • Prevents oil flow from the online pump to the offline pump

Check valves help you prevent backflow in a hydraulic system while control valves help you regulate the speed of the fluid flow in the hydraulic system. With all the different types of hydraulic valves, you need to choose the right one in order to get the job done.

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:

What is the difference between Hydrant Valve & Landing valve?

Landing valves are something that is used for fighting fires and is provided on risers in buildings. These are usually located in staircase landings, allowing easy access to firefighters. A fire hydrant system is comprised of water supply pipework and valves, which can be connected to the hose of fire brigades for firefighting purposes. Hose reel drum and hose pipe are also effective in fighting fires inside a building. Both the hydrant valve and landing valve have similar designs, irrespective of the place installed. Flow Control Valve is a device that is used to control the flow of water by varying the size of the flow directed by a signal from a controller. 

Difference between Hydrant Valves & Landing Valves:

Landing Valve

Landing valves are permanently charged with water using a pressurized supply. In simple words, they are globe valves, installed on hydrants. Also, a hose and a branch are connected to a coupling on it. Landing valves are installed in all the floors of a building where installation of hydrant valve is not possible and is then used by fire fighting department to extinguish the fire. The normal pressure of a landing valve is around 65 psi. In order to keep the nominal working pressure at the inlet of the hose reel, a pressure reducing valve is used in hose reel system.  

Hydrant Valves

Fire Hydrant Valves are efficient in fighting large fires. They allow firefighters to extinguish the fire from a distance. Pumping facility is the most important part of the fire hydrant system. The main use of the pump is to pull the water from the reservoir and supply the same pressure to the hydrant points enabling firefighters to extinguish the fire effectively. In order to connect and operate fire fighting equipment from a hydrant valve, the pressure rating must be 100 psi (7 kg/cm2). But, it varies depending on the size of the building. The pressure of hydrant valves in large industrial complexes might range around 10-11 kg/cm2 while in small buildings it might range around 4-5 kg/cm2.  

Fire sprinklers and flexible hoses can be effective in fighting small fires. Fire sprinklers discharge water when the effect of fire or extensive heat is detected and is effective in the early stage of fire. Flexible hoses act as a connection between the pump to the system. The standard length of a flexible hose is around 100 ft.  

If you’re looking for fire fighting instruments, SKG PNEUMATICS INC might be the best choice, with more than 14 years of experience they deliver quality instruments of highest standards.

Different Types Of Hydraulic Valves

Hydraulic valves direct any type of flow of liquid medium through a hydraulic system and control the flowing fluid. There are different systems utilized in hydraulic to enable this to happen. Valves can be precisely worked (by handle, handle or cam), electric solenoid-worked, or pilot-worked (air or water powered weight incites the valve). A few valves utilize the weight of the circuit’s liquid to activate themselves, as with alleviation valves. Valves can likewise be incited with links, switches, plungers, torque engines, etc. There are many industrial valves supplier in the market which provides different types of valve for various purpose in which the most common valve the use water valve. Here some other valves which we supply to our clients.

Hydraulic Pressure Reducing Valve

Hydraulic pressure valve exerts its pressure by the hydraulic fluid in all the direction and exerts the force per unit area. Thus hydraulic pressure is used in various hydraulic systems like jaws of life, metal shears, automobile brakes, car crusher etc.

Butterfly Valve

A valve comprising of a pivoting round plate or a couple of pivoted half-circle plates appended to a transverse shaft and mounted inside a pipe so as to manage or forestall stream. Butterfly valves work comparatively to ball valves. Pivoting (rotating) the handle, either physically or with a pneumatic framework, turns the plate opposite or parallel to the stream of the liquid.

Hydraulic and Pneumatic Valve

A solenoid valve is an electrically enacted valve, regularly used to control the stream or heading of air or fluid in liquid power frameworks. Solenoid valves are utilized in both hydraulic pressure and pneumatic pressure power system, and regularly in either poppet or spool arrangements.

Check Valve

A check valve, non-return valve, reflux valve, maintenance valve or single direction valve is a valve that ordinarily permits liquid (fluid or gas) to course through it in just a single bearing.

Globe valve

It has a unique relation to ball valve, is a sort of valve utilized for controlling stream in a pipeline, comprising of a portable plate type component and a stationary ring seat in a for the most part round body. These globe valves are generally used in the petroleum industry.

Ball valve

A ball valve is a type of quarter-turn valve which utilizes an empty, punctured and rotating ball to control move through it. It is open when the ball’s gap is in accordance with the stream and shut when it is turned 90-degrees by the valve handle. The handle lies level in arrangement with the stream when open, and is opposite to it when shut, making for simple visual affirmation of the valve’s status.

Ball valves are solid, performing great after numerous cycles, and dependable, shutting safely even after extensive stretches of neglect. These characteristics settle on them a brilliant decision for shut off and control applications, where they are frequently linked to doors and globe valves, yet they come up short on their fine control in throttling application.
