The Pneumatic shut-off butterfly valve can quickly cut off the medium flow in the pipeline. The pneumatic actuator is spring type. It is widely used in the gas waste heat power generation system and steam extraction heat supply steam turbine system as a system safety guarantee. It closes quickly and has low flow resistance.
Pneumatic shut-off butterfly valve
- Quick closing time of 0.3 seconds, emergency cut-off safe and reliable;
- 2, Triple eccentric metal seal structure, flexible, convenient opening and closing seal zero leakage;
- Room temperature medium can choose double partial softhearted sealing structure, low cost, reliable sealing;
- Close the end of the buffer,effectively avoid valve inertial impact;
- Can use spring to realize fast, can also use accumulator to realize fast, two forms of the same safe and reliable
