Double eccentric pneumatic high-performance butterfly valve
Alternative name: soft seal pneumatic high-performance butterfly valve_wafer type pneumatic high-performance butterfly valve
Model: D672F-150LB, D672F-300LB
Features of high-performance butterfly valve:
High performance butterfly valve The butterfly valve adopts a double eccentric structure. The two eccentricities of the valve stem and butterfly plate enable the valve to be sealed immediately when it is opened, reducing friction loss and improving service life. The mechanical friction coefficient of the sealing surface is only 0.07 when the double eccentric butterfly plate is matched with the arc face valve seat. The wear is very small, the opening and closing are easy and free, and the service life is effectively extended. The no-load detection reaches 600000 times of opening and closing without leakage.

Advantages of pneumatic high-performance butterfly valve:
The pneumatic high-performance butterfly valve deviates from the center of the valve body structure at the center of the shaft. In combination with the design of the circular sealing surface of the valve plate, the valve plate quickly disengages from the sealing seat when opening to reduce the friction force of the sealing surface. The valve plate has better sealing performance when closing. The structural design of the center self sealing valve seat combined with the independent compensation seal of the valve seat can effectively compensate the wear of the valve seat, and reduce the friction force during sealing, so that the operating force of the valve can be greatly reduced and the control degree of the butterfly valve can be effectively improved.
