Fork type pneumatic cut-off butterfly valve can quickly cut off the flow of medium in the pipeline. It adopts a single acting cylinder and a spring type pneumatic actuator. Widely used in gas waste heat power generation systems and extraction heating steam turbine systems as a system safety guarantee. Close quickly with low flow resistance.
Fork type pneumatic cut-off butterfly valve 
0.3 seconds quick shutdown time, safe and reliable emergency cut-off; 2. Triple eccentric metal sealing structure, flexible and convenient opening and closing, zero leakage sealing; At room temperature, a dual local soft core sealing structure can be selected for the medium, which is low-cost and reliable in sealing; Close the end of the buffer to effectively avoid valve inertia impact; It can be achieved quickly using springs or accumulators, both of which are equally safe and reliable
