Pneumatic piston quick shut-off valve
Brand:Pneumatic eccentric butterfly valve 型号:ZQGP
气动快速切断阀Composed of a domestically launched pneumatic multi spring piston actuator and a low flow resistance, dual sealing structure cut-off valve. The actuator has fast action speed, high thrust, self resetting function, and a manual control mechanism; The valve body flow path is unobstructed, the flow coefficient is large, and the valve core and seat have elastic and rigid cascade dual seals. The novel structure makes this product a high-performance new type of shut-off valve with fast action, tight shut-off, safety and reliability.
