Gate Valve opens shuts is the damper plate, the damper plate heading and the fluid direction is vertical, the gate valve only can do all starts with the entire pass, cannot make the adjustment and the throttle. The damper plate has two packing surfaces, but the most commonly used pattern gate valve two packing surfaces form, the wedge-shaped angle wedge-shaped along with the valve parameter different, usually is 50, medium temperature not Gao Shiwei 2°52'.The wedge type gate valve damper plate may make a whole, the named rigid damper plate; Also may make can produce the micro distortion damper plate, improves its technology capability, the atonement packing surface angle the deviation which produces in the processing process, this kind of damper plate named elastic damper plate.The stainless steel gate valve material quality divides into 304 stainless steel gate valves, 316 stainless steel gate valves, 321 stainless steel gate valves.Expressed the method is: Z41H-16P.
