D671F4-16 D671F4-16C D671F4-16P Pneumatic lined butterfly valve

Overview of D671F4-16 D671F4-16C D671F4-16P Pneumatic lined butterfly valve

D671F4-16 D671F4-16C D671F4-16P Pneumatic lined butterfly valve adopts PTFE butterfly dish with spherical sealing surface. The valve has light operation, limited sealing performance and long lifespan. It can be occasions requiring reliable sealing and good adjustment characteristics. The valve body adopts divided type, and the sealing at both ends of the control device shaft is by adding fluororubber on the rotating base surface between the butterfly plate and the valve seat, Ensure that the valve shaft will not contact the fluid medium in the cavity.
