Pneumatic Butterfly Valves Manufacturers

ZECO Valve is a leading Pneumatic Butterfly Valve supplier, manufacturer, and exporter in the valve industry. These valves are highly preferable because of their durability and extended life. Valves of various pressure classes are available with us. We also provide Single-acting and double-acting pneumatically operated butterfly valves. These valves are classified as quarter-turn valves. It may be installed between two flanges in a rigid pipe system and is also appropriate for vacuum applications, which is why it is the first choice of clients. We manufacture Actuated Butterfly Valves in numerous body types and sizes according to their usage and performance.

Working Principle of Pneumatic Butterfly Valve

The pneumatic Butterfly valve works on a simple mechanism and is easy to use so it has low maintenance, these valves are fitted in mid of fluid flow. There is a disc connected to a center rod, which rotates the disc quarterly to pass through to open and close. This metal disc called Butterfly, rotates a quarter turn to allow fluid to pass indefinitely and so on the slow opening valve will reduce the flow, and the turning of the disc to close the valve and flow. This valve is operated by pressurized air which is controlled by a pneumatic actuator that is fixed on it. So there is nobody who needs to operate but the pneumatic actuator operates this valve too fast and easily with the lowest cost and safety.

Pneumatic Butterfly Valve Applications

Pneumatic Actuator Butterfly Valves are generally used for liquid and slurry materials. These are very popular in the valve industry because of their easy-to-use and simple mechanism. Pneumatic Butterfly Valves are very useful to control highly inflammable liquids like petro-chemicals, Oil, and Gas. It is operated by Pneumatic which allows fast functionality and is safe from fire and electric short circuits. So it is an electricity-efficient operated valve with the lowest cost.

Advantages of Pneumatic Butterfly Valves

Disassembly and maintenance are simple thanks to their small size and low weight. They can be placed in almost any location
The structure is simple and compact. Operating torque is low. Opening rotates 90 degrees in a flash
The features of the flow are that of a straight path. The regulating ability is excellent
The no-pin connection between the butterfly plate and the valve stem eliminates the chance of any internal leaking
The butterfly valve’s outer sphere has a spherical shape, which improves sealing performance and extends the valve’s service life. After more than 50000 repetitions of entry and exit under pressure, there is still no leakage
It is possible to change the sealing item. Two-way sealing is possible because the sealer is so reliable
The butterfly plates can be covered with a coating, such as PTFE or nylon, depending on the needs of the user
Flange and clip connections are two options for pneumatic butterfly valves
Manual, electrical, or pneumatic operating options are available

Air Butterfly Valve – Air Actuated Butterfly Valve – Pneumatic Butterfly Valve Manufacturer

What is Air Actuated Valve?

An air-operated valve, also known as a pneumatic valve, is a type of power-operated pipe valve that uses air pressure to perform a function similar to a solenoid. As air pressure is increased, the compressed air starts to push against the piston or diaphragm walls which causes the valve to actuate. Whether the valve opens or closes depends on the application. These valves are used for many functions in pneumatic systems, but most often serve one of two functions. The first activates a part of the system when a specific pressure is reached. The second prevents damage by maintaining a constant pressure or flow rate inside a system or releasing pressure when it reaches excessive levels.

What is Air Actuated Butterfly Valve?

Air Actuated Butterfly Valve is composed of a pneumatic actuator and butterfly valve. The basic working principle of the pneumatic valve is that compressed air enters the pneumatic actuator to drive the piston, and then the rotating or lifting torsion shaft drives the stem. Pneumatic Butterfly Valve is a circular disc rotating with the stem as an opening and closing function, in order to achieve the opening action of the pneumatic valve, mainly for the use of a cut-off Valve, can also be designed to have the function of regulation or section valve and regulation At present, the use of butterfly valve in low pressure large and medium diameter pipeline is more and more.

Air actuated soft seated butterfly valve for on-off control of water and other media compatible with the materials of construction. Wafer-style valve sandwich mounts between standard ANSI /ASME B16.5 Class 150 flanges and other international standards. Double-acting actuators use an air pressure signal (80-120 PSI) to open and close the valve.

How does a Pneumatic Butterfly Valve work?

The “butterfly” is a disk connected to a rod. When the valve opens, the disk rotates to allow fluid to pass through. It closes when the rod rotates the disc by a quarter turn to a position perpendicular to the flow direction. Learn more about how butterfly valves work and when to use them for different applications.

Types of Air Butterfly Valve

Pneumatic Butterfly Valve is divided into Spring Return(Single Acting) Pneumatic Butterfly Valve and Double Acting Pneumatic Butterfly Valve.

Spring Return(single acting) pneumatic actuator is the spring-driven Piston structure, there are two principles: normally open(NO) and normally closed(NC), which means that: when air goes in, the valve closed(NO); when air goes in, the valve opened(NC).

Double Acting pneumatic valves need to be equipped with a 5-way 2-position solenoid valve to control the air going into the different entrances and then control the valve open and close. When driving the same valve body, the opening and closing speed of double acting is faster than the single acting.

Advantages of Pneumatic Butterfly Valve

The main advantages of the pneumatic actuator butterfly valve, are simple structure, small size, lightweight, and low cost, pneumatic butterfly valve this feature is particularly significant, installed in a high-altitude tunnel, through two-five-way solenoid valve control easy to operate, but also can adjust the flow medium.

Features Of Air Butterfly Valves:

Small and light, easy to disassemble and repair, and can be installed in any location
The utility model has the advantages of simple and compact structure, small operating Torque, and quick 90-turn opening
Large size range for selection
