FORGED STEEL FLANGED GATE VALVE

Forged Steel Flanged Gate Valve Descriptions

Forged steel flanged gate valve API602 is the most common type of valve in the oil & gas filed and power plant, because they can be applicable to water, oil and gas with high temperature and high pressure. Our forged steel gate valve is available with materials of steel ASTM A105N, alloy steel A182 F11, A182 F22, stainless steel A182 F304/L, A182 F316/L, A182 F5, duplex SS A182 F51, low temperature steel A350 LF2, with ends connection of socket welded, butt-welded, threaded, welded flanged and integral flanged. We can produce especially with extended body, extended bonnet, locking device and low temperature.
