What is a gate valve?

- Oct 22, 2019-

The opening and closing direction of the valve is perpendicular to the direction of the airflow, and the valve is mainly used to cut off the clean gas.


Gate valves can be classified into hot air valves, cold air valves, combustion valves, gas valves, flue valves, and waste air valves.


1. Prevent the media from flowing backwards;

2. Adjust the medium pressure and flow rate;

3. Switching on and off the medium;

4. Separating, mixing or distributing the medium;


a, the flow resistance is small. The inner medium passage of the valve body is straight through, the medium flows in a straight line, and the flow resistance is small.

b. It is more labor-saving when opening and closing. Compared with the shut-off valve, the direction of movement of the gate is perpendicular to the flow direction of the medium, whether it is open or closed.

c, is not easy to produce water hammer phenomenon, because the closure time is long

d. The medium can flow in any direction on both sides, which is easy to install. The gate valve channels are symmetrical on both sides. e, simple shape, short structure length, good manufacturing process, wide application range

f, compact structure, good valve rigidity, smooth passage, small flow resistance, stainless steel and hard alloy sealing surface, long service life, PTFE packing. Sealed reliably. Light and flexible operation.
