Specifications

Reduce the rotational torque, support the stem, and make it separate from the valve body effectively, reduce the wear of the valve stem.

after polishing treatment, with the valve seat precision.

to achieve zero leakage of air tightness test requirements, the opening and closing torque is small, extend the service life of the valve seat.

Stem seal is not easy to deform, thereby avoiding the usual stem leakage.
