PRESSURE SEAL BONNET Y GLOBE VALVE

Pressure Seal Bonnet Y Globe Valve Descriptions

Pressure seal bonnet Y globe valve is one type of forged steel globe valve in the oil & gas field and power plant, because they can be applicable to water, oil and gas with high temperature and high pressure. Forged steel globe valve can be divided into socked welded globe valve, butt-welded globe valve, threaded globe valve, flanged globe valve, Y type globe valve, with materials of steel ASTM A105N, alloy steel A182 F11, A182 F22, stainless steel A182 F304/L, A182 F316/L, A182 F5, duplex s.s. A182 F51, low temperature steel A350 LF2, with ends connection of socket welded, butt-welded, threaded, welded flanged and integral flanged. We can manufacture the pressure seal bonnet Y globe valve especially with extended body, extended bonnet, locking device and low temperature.
