ANSI150 resilient seated double flange gate valve
Gate valve switch is a ram, ram movement direction perpendicular to the direction of flow with the gate valve can only be fully open and close, not to adjust and throttling.Wedge gate valve of the damper can be made into a whole body, is called a rigid disc;Can also make it generates trace of deformation of ram, in order to improve the manufacturability, make up for the sealing surface Angle in the process of our processing deviation, this damper is called elastic disc.Stainless steel gate valve material is divided into 304 stainless steel gate valve, 316 stainless steel gate valve.
Gate valve may have flange ends which are drilled according to pipeline compatible flange dimensional standards. Gate valves are typically constructed from cast iron, ductile iron, cast carbon steel, gun metal, stainless steel, alloy steels, and forged steels.
