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.

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.

The Advantages, Application & Components of Butterfly Valves

A butterfly valve considered as a regulating device which is used to shut off the flow of a fluid. It is also known as quarter turn valves because it provides 90-degree rotary motion for the stoppage. They often came in large sizes but short in length and are of the very lightweight. They possess very low torque requirements. It is used with globe and ball valves in some applications. 

Advantages

Butterfly valves are the best choice for all kinds of butterfly valve requirements. These are very cost effective and the performance of the product is also very high. These valves are similar to ball valves but have a little more advantages. The dist in the butterfly valve is lighter than a ball and it requires less structural support than a ball valve. Butterfly valve does not require high maintenance and hence widely used in industrial applications. They also require a little space and it is very easy to open them. 

Components

There are four main components of a butterfly valve: body, disk, stem, and seat.

1. Butterfly valve body

The body of the butterfly valve fits between two pipe flanges. It is one of the main components of the butterfly valve. Lug and wafer body design are most common among them.

2. Butterfly valve disk

The disk is used to stop the flow of the liquid. The disk of the butterfly valve has a number of variations in its design and orientation to improve the flow, sealing or torque.

3. Butterfly valve stem

 It is available in two design one- piece shaft or two-piece design. For the proficient selection of the material with respect to its cost as well as mechanical properties, it is confined from the media.

4. Butterfly valve seat

It provides the shutoff between the disk edge and the seat. Elastomers and polymers are used to make the seat of the butterfly valve. It may be bonded with the body or may be locked in.

Applications

Some of the common applications of the butterfly valve are: 

On/ off isolation, Dead- end service, heating, ventilation, and air conditioning system, Industrial process piping, Municipal raw water intake, Municipal chlorinated water systems (2000 ppm), Municipal feed water and reservoir, throttling and process control, full vacuum, blower installations.

Wafer And Lug Type Butterfly Valves

Butterfly valves are generally used in chemical or food industries to regulate or isolate the flow of liquid, gas and solid. The valve manufacturers are in high demand and new companies of valve manufacturers are rising in the market rapidly. We as SKG Pneumatics Inc, Butterfly Valve Suppliers and Industrial Valve dealers in India offer high-quality valve as the demand is growing.

TYPES OF BUTTERFLY VALVES AND DEMAND

POPULAR BUTTERFLY VALVES

When it comes to the butterfly valve, there are four types including Wafer type end, lug type ends, butt welded type ends and both flanged ends. They have a wide demand in several industries like sugar, oil, chemical industries etc. Butterfly valves, mainly the wafer valves and lug type valves are always tested to meet industrial requirements.

DIFFERENCE BETWEEN WAFER AND LUG TYPE VALVES

The wafer body type valve is easy to install but cannot be used as the isolation valve. They don’t have attachment lugs. On the other hand, Lug type valves have lugs attached to the flanges on the end and can be removed easily.

DEMAND OF BUTTERFLY VALVES

Butterfly Valves are in high demand because these valves can be used even in high-pressure services. Butterfly valves need less time to open and close, thus maintenance costs compared to other valves like ball valves.

ADVANTAGES OF BUTTERFLY VALVES

Due to its lightweight design and compact nature butterfly valves is suitable as compared to other valves. They are most popular and high in demand among the Valves Suppliers in Delhi.  They can be widely used in cooling water, fire fighting, vacuum services with good performance.

OTHER TYPE OF BUTTERFLY VALVES EXCEPT FOR THE WAFER AND THE LUG

While the wafer type cannot be used as a pipe end, lug type can be used as a pipe end. The other two form of butterfly valves mainly the welded one is used for high-pressure applications.

With the demand of valves growing in the Indian market other valves like balancing valves, a globe valve, ball valve has also increased. Although, butterfly valves still remain the most popular particularly because of its low cost and easy installation.

Types of Pipe valve

A valve is a device that can control the flow and pressure of the fluid in a pipe. A few either starts or altogether stops the flow of fluid whereas there are some that partially obscures the path.

The different types of pipe valves are explained below in detail.

Ball Valves

Ball valves operate with a quarter-rotary motion. In a ball valve, the flow path is manipulated by the ball-shaped disk which requires a 90-degree turn of the valve handle. It is comparatively smaller in size and lighter than a gate valve.

Butterfly Valves

Butterfly valve can start, stop, and regulate the flow path but only to some extent. It is a simple valve that can be operated by a 90-degree turn of the valve handle. A butterfly valve is not normally designed to give a positive shut-off but modern technology has provided room for improvement in its blueprint. This valve is now capable of a bubble-tight shut-off.

Check Valves

Check valves, or NRVs (non-return valves), supports the unidirectional flow of fluid only. Their function is to check backflow. In check valves, backflow is prevented by “stoppers”. The different kinds of “stoppers” are ball, piston, and swing. Ball and piston check valves work by demanding a little amount of inbound flow pressure. The movement of fluid in a swing check valve is through a pivoting flap which opens only in one direction and ensures that there is no backflow.  

Gate Valves

Gate valves are the most ordinary and the most frequently sold valve type in the industrial valve trade. These act as a block valve for isolating pipe systems since their properties are limited to either opening or closing. There is no restriction in the flow path once a gate valve is opened as it opens all the way. Gate valves are preferred in a straight-line system that requires minimum obstruction. You can regulate a gate valve with the help of a hand-wheel or a piston actuator.

Pressure Reducing Valves

If you are looking for a device to reduce the water pressure, pressure reducing valve is your answer. These valves get down to work by bringing down the quantity of water that flows through a pipe. With the valve, water that was pushing through the pipes at high pressure will be efficiently slowed down.
