Pneumatic Wafer-Type Butterfly Valve

Writer:Fanny KangSource:Network Date:2017-5-19 17:19
The operation principle of pneumatic wafer type butterfly valve is based on the main control valve rotation of the valve to open and close, mainly in the pipeline system to intercept and distribute the role of the fluid. Pneumatic wafer-type butterfly valve is the preferred pipeline recommended conventional butterfly valve, with a simple structure, flow resistance coefficient is small, the flow characteristics tend to straight line, will not stay debris. And has the advantages of light weight, easy installation, less driving torque. Is widely used in various areas of the pipeline system.

Characteristics of Pneumatic Wafer Type Butterfly Valve
1, small and lightweight, easy disassembly and maintenance, and can be installed in any position.
2, simple structure, compact, small operating torque, 90 ° turn open quickly.
3, the flow characteristics of a straight line, good regulatory performance.
4, butterfly plate and the stem connection with no pin structure, to overcome the possible leaks.
5, butterfly plate cylindrical spherical shape, improve the sealing performance and extend the service life of the valve, with pressure to open and close more than 50,000 times still maintain zero leakage.
6, the seal can be replaced, and sealed to achieve a two-way seal.
7, butterfly plate can be sprayed according to user requirements, such as nylon or polytetrafluoroethane.
8, the valve can be designed to flange connection and folder connection.
9, the drive can choose manual, electric or pneumatic.
The application scope of Pneumatic butterfly valve 
Pneumatic butterfly valve for temperature ≤ 120 ℃ or ≤ 150 ℃, nominal pressure ≤ 1.6MPa Water supply and drainage, sewage, food, heating, gas, shipbuilding, hydropower, metallurgy, energy systems and textile industries, especially for two-way sealing And the valve body is easy to rust, for regulating the flow and cutoff media.
