Product main features:

1、High performance regulating cut-off type. That can be used as a regulating valve, and can be used as a cut-off valve.
2、Excellent gas and liquid isolation function and flow control characteristics.
3、Small opening and closing friction at the valve seat, no stagnation, long service life.
4, easy to replace and adjust the sealing performance of the sealing ring
5、Low operating torque and reliable torque shut-off.
6、Can be designed into fireproof structure according to customer's demand.

Structural features:

Due to the double eccentric structure, the butterfly plate is gradually detached from the valve seat during the valve opening process, which reduces the friction between the sealing surfaces, thus prolonging the service life. The valve seat adopts lip structure design, and the material is made of PTFE, RPTFE or ultra-high molecular weight polyethylene, no matter what the direction of fluid is, the valve seat can always return to the original position after deformation, so as to ensure the sealing.
