What are the characteristics of gate valve

Gate valve is an open and close part of the gate, the movement of the gate and the direction of the fluid vertical, gate valve can only be fully open and closed, can not be adjusted and throttle.Gate valves are sealed by the contact between the seat and the gate, usually with metal surfacing to increase wear resistance, such as surfacing 1Cr13, STL6, stainless steel, etc.The gate has rigid gate and elastic gate, according to the different gate, the gate valve is divided into rigid gate valve and elastic gate valve.

Gate valve is a kind of valve with a large amount of consultation every day. It is commonly used in water supply system. The characteristics of gate valve are as follows:

1.Low flow resistance.The medium channel inside the valve body is straight through, and the medium flows in a straight line. When the gate is fully open, the resistance inside the valve body channel is almost zero, and the flow resistance is very small.

2.Opening and closing saves effort.Whether gate valve is open or closed, the movement direction of the gate is perpendicular to the flow direction of the medium, the resistance of the gate to do lifting movement is also very small, opening and closing is very labor saving.

3.Fully open and fully closed gate valves require a long journey, and the closing time is relatively long, which also makes the phenomenon of water hammer not easy to occur.

4.Gate valve channel is symmetrical on both sides, the installation is not limited by the direction of medium flow, convenient installation.

5.Simple shape, short structure length, good manufacturability, wide application.

6.Widely used. Gate valves are made of gray cast iron, ductile iron, cast steel, stainless steel, forged steel and other materials.
