Structural characteristics of pneumatic eccentric hemispherical valve

Open and close without friction

This function completely solves the problem of traditional valves affecting sealing due to mutual friction between sealing surfaces.

top loading structure

The valve installed on the pipeline can be inspected and repaired directly online, which can effectively reduce the shutdown of the device and reduce the cost.

single seat design

It eliminates the problem that the medium in the cavity of the valve affects the safety of use due to abnormal pressure increase.

low torque design

The valve stem with special structural design can be easily opened and closed with only a small handle.

Wedge seal structure

Pneumatic eccentric hemispherical valve is the mechanical force provided by the valve stem, and the ball wedge is pressed onto the valve seat to seal, so that the sealing performance of the valve will not be affected by the change of pipeline pressure difference, and the sealing performance can be guaranteed under various working conditions ensure.

Self-cleaning structure of the sealing surface

When the ball tilts away from the valve seat, the fluid in the pipeline passes evenly at 360° along the ball sealing surface, which not only eliminates the local erosion of the valve seat by the high-speed fluid, but also washes away the accumulation on the sealing surface, achieving the purpose of self-cleaning .
