D643HAir Actuated Butterfly ValveProduct Overview:
The pneumatic butterfly valve consists of a pneumatic actuator and a butterfly valve. The pneumatic butterfly valve operates with a circular butterfly plate that rotates with the valve stem, used primarily as a cutting valve to achieve the actuation action. It can also be designed with regulating or segment valve functions. The use of butterfly valves in low-pressure large and medium-sized pipe diameters is increasingly common. Categories of flanged pneumatic butterfly valves: Flanged hard-seated pneumatic butterfly valve, flanged soft-seated pneumatic butterfly valve, flanged carbon steel pneumatic butterfly valve, stainless steel pneumatic butterfly valve.
D643HAir Actuated Butterfly ValveParameter Introduction:
The butterfly plate of the pneumatic butterfly valve is mounted in the diameter direction of the pipeline.Butterfly valveWithin the cylindrical channel of the valve body, the round disk butterfly plate rotates around the axis, with an angle of rotation of0°-90°, rotate to90° At that time, the valve is fully open. The butterfly valve has a simple structure, small size, and light weight, consisting of only a few parts. Moreover, it only requires a turn90°Quickly open and close, easy to operate, and the valve boasts excellent fluid control characteristics. When the butterfly valve is fully open, the thickness of the butterfly plate is the resistance to the medium flowing through the valve body, hence the pressure drop generated by the valve is minimal, providing good flow control properties. Butterfly valves come in two sealing types: elastic seal and metal seal. The elastic seal valve has seals that can be mounted on the valve body or attached around the butterfly plate. Valves with metal seals generally have a longer lifespan than those with elastic seals but are challenging to achieve a perfect seal. Metal seals can withstand higher working temperatures, while elastic seals have the drawback of being temperature-sensitive. If the butterfly valve is to be used for flow control, it is crucial to select the correct size and type of valve. The structural principle of butterfly valves is particularly suitable for manufacturing large-diameter valves. Butterfly valves are widely used in general industries such as oil, gas, chemicals, water treatment, and also in the cooling water systems of thermal power plants. Common pneumatic butterfly valves include pneumatic wafer-type butterfly valves and pneumatic flanged butterfly valves. The pneumatic wafer-type butterfly valve is connected between two pipe flanges using double-head bolts, while the pneumatic flanged butterfly valve has flanges on the valve, and the flanges on both ends of the valve are connected to the pipe flanges with bolts.
