Oxygen valve is widely used in various coal chemical equipment, chemical, petrochemical ,steel and metallurgy industries. Because the medium is oxygen (combustion imp rover),Any internal or external leakage will cause an fire or explosion etc. disasters. So that there is an extremely high requirement on the sealing performance , material characters, operation speed, service life of oxygen valves. The metal seated ball valve used for oxygen service is coated by unique hard alloy which can thoroughly achieve the quick shut-off or opening of pure oxygen supply pipeline or oxygen weeping pipeline.
