Overview
Forged steel globe valve is one important type of valve in the oil & gas field and power plant, because it can be applicable to water, oil and gas with high temperature and high pressure. Forged steel globe valve can be divided into socket 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 and low temperature steel A350 LF2. And also, extended body, extended bonnet, locking device and low temperature is available as optional. Flowspec Luokai can manufacture the forged steel globe valve in accordance with API602, ASME B16.34 and BS5352. Welcome to contact us for detailed information and best quotes if you have any questions or inquiries.
