Pneumatic Wcb Wafer Butterfly Valve

Pneumatic butterfly valve is a type of valve that uses a circular butterfly plate that rotates with the valve to achieve opening and closing, and is mainly used as a block valve to achieve activation. It can also be designed to have the function of regulating or regulating both section valves. Disc valves are increasingly used in low-pressure large and medium diameter pipelines.

Butterfly valves have a simple structure, small size, and light weight, consisting of only a few components. And it only needs to rotate 90 ° to quickly open and close, with simple operation. At the same time, this electric valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the single resistance of the medium flowing through the valve body, so the pressure drop generated through the valve It is very small, so it has good flow control characteristics. Butterfly valves have two sealing types: elastic sealing and metal sealing. Elastic sealing valve, the sealing ring can be embedded on the valve body or attached around the butterfly plate.

If butterfly valves are required for flow control, the main thing is to choose the correct size and type of valve. The structural principle of butterfly valves is particularly suitable for making large-diameter valves. Butterfly valves are not only widely used in general industries such as petroleum, gas, chemical, and water treatment, but also in the cooling water system of thermal power plants.

Product Characteristic

1. Compact and lightweight, easy to disassemble and repair, and can be installed in any position.
2. The structure is simple and compact, with low operating torque and quick opening of 90 ° rotation.
3. The flow characteristics tend towards a straight line, with good regulation performance.
4. The connection between the butterfly plate and the valve stem adopts a pin free structure, which overcomes the possible internal leakage points.
5. The outer circle of the butterfly plate adopts a spherical shape, which improves the sealing performance and extends the service life of the valve. It can be opened and closed under pressure for more than 50000 times and still maintain zero leakage.
6. The sealing components are replaceable and the sealing is reliable, achieving bidirectional sealing.
7. Butterfly plates can be coated with coatings such as nylon or polytetrafluoroethylene according to user requirements.
8. This valve can be designed for flange connection and clamp connection.
9. The driving mode can be selected as manual, electric or pneumatic.
