Products Introduction

Oxygen valve is widely used in various coal chemicalequipment, chemical, petrochemical ,steel and metallurgy industries. Becausethe medium is oxygen (combustion imp rover),Any internal or external leakagewill cause an fire or explosion etc disasters. So that there is an extremelyhigh requirement on the sealing performance , material characters, operationspeed, service life of oxygen valves. The metal seated ball valve used foroxygen service is coated by unique hard alloy which can thoroughly achieve thequick shut-off or opening of pure oxygen supply pipeline or oxygen weepingpipeline.
