Gate valves are a type of valve with a large volume of inquiries per day. They are commonly used in water supply systems. The advantages of gate valves are:

1. Low flow resistance.The medium channel inside the valve body is straight 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 the gate valve is open or closed, the direction of the gate movement is perpendicular to the direction of the medium flow, the resistance of the gate movement is also very small, opening and closing is very labor-saving.

3, the gate valve fully open and fully closed need a long trip, the closing time is relatively long, which also makes the water hammer phenomenon is not easy to produce.

4. Both sides of gate valve channel are symmetrical, and the installation is not restricted by the flow direction of medium, which is convenient for installation.

5, simple form, short structure length, good manufacturing technology, wide range of application.

6, wide use, gate valves have gray iron, ductile iron, cast steel, stainless steel, forged steel and other materials, different materials can be used in different working conditions, wide range of applications.
