Flange iron non rising stem gate valve

Gate valve refers to a valve whose opening and closing body (valve plate) is driven by the valve stem to lift the sealing surface of the valve seat, which can connect or cut off the passage of fluid. When the valve is partially opened, eddy currents are generated on the back of the gate, which can easily cause erosion and vibration of the gate, and also damage the sealing surface of the valve seat, making repair difficult. Gate valves are usually suitable for working conditions that do not require frequent opening and closing, and maintain the gate fully open or fully closed. Not suitable for use as a regulator or throttle.

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.
