Forged Steel Gate Valve

Summary

A compact but extremely sturdy design for high pressure-temperature service.
Stainless steel A182 F316(L) wedge ensures low friction and long service life.
For Class 1500 valves and for steam service.
Packing rings are precompressed to provide a high integrity seal.
For welded bonnet valves, the bonnet is threaded in and torqued to an engineered torque value and the body bonnet joint is strength-welded, offering double protection against leakage. (Body / bonnet threads and strength-weld).
