Hard seal pneumatic ball valve

POV metal seal ball valve with the characteristics of high pressure,

high temperature resistance, strong shear force, etc. Using fixed ball core,

reducing the high pressure deformation defects, valve core surface hardened

coating and paired grinding, stem seal with the pre-pressing graphite packing,

reduce the possibility of leakage.
