Large diameter pneumatic hard seal butterfly valve pictures

Large-diameter part adopts pneumatic hard seal butterfly valve pneumatic valve body design of principle of triple eccentric pneumatic valve seat adopt hard and soft sealing compatible with multilayer structure, with excellent cutting performance and durability, is on the pipeline to adjust flow, truncation, or the best device connected to the fluid. Triple eccentric choose different material, pneumatic butterfly valve can be used for the operation condition of the different medium, the highest working temperature is 600 ℃.



principle of pneumatic hard seal butterfly valve:

butterfly plate sealing surface designed to relative axis of butterfly plate is a truncated cone surface, made with butterfly plate seal face a pneumatic valve seat sealing surface contact Angle, the Angle of contact face evenly around the circumference of a circle is equal to a narrow cuneate, and butterfly plate the circumference of a circle the seal line is reasonably elliptic curve, longitudinal sealing compensation effect on both.
