Forged Steel Gate valves
According to API 602 and ANSI B16.34 standard, forged steel gate valve is designed and manufactured. It has Flanged End standard,Inner Screwed standard,Butt-Welded standard and Socket Welded standard four types, and the standard for it is ANSI B16.5 (RF), ANSI B1.20.1, ANSI B16.25, ANSI B16.11, respectively. The standard for face to face is ANSI B16.10. In addition,the test standard is API 598. Even under pressure Class 150 to Class 2500, it can work very well. The material mainly used for building the valve is A105, A250 LF2/F5/F11/F22, A180 F304/ F304L / F316/ F316L.
