Product overview

Oxygen special copper fixed ball valve belongs to the special valve for oxygen pipeline, in addition to the characteristics of ordinary valves, but also in view of its use of high-quality copper or stainless steel material manufacturing, but also has the advantages of corrosion resistance, good flame retardant performance, good electrical conductivity, fast heat transfer and so on. Designed with anti-static, fire-resistant structure, each part in the assembly strictly degreasing treatment. Valve body and other components selected high quality silicon brass and pickling, passivation, inspection and test with pure tap water without any grease for high pressure seal test, with 0.6MPa gas leakage test, valve without leakage; After special process treatment, this kind of ball valve is not only fast and easy to operate, small flow resistance, safe and reliable, but also long service life (small scouring of the sealing pair).


Product characteristics
1, the parts in the assembly of strict degreasing treatment.
2, the operation torque is small, in addition to the long-term sealing of the sealing grease, making the operation more flexible.
3. Conductive spring is arranged between the valve stem and the valve body and the valve stem and the ball, with a fireproof and anti-static structure.
