Product features：

The handwheel gate valve moves linearly with the valve stem, which is called the lifting stem gate valve (also called the rising stem gate valve). Some gate valves and stem nuts are installed on the gate, This kind of valve is called a non-rising stem gate valve. The gate valve design scheme is used to open or close the part without using a throttling device. The most common gate valves are knife gate valves and wedge gate valves.

Gate valve: It is used as a key to disconnect the material on the drainage pipeline, and the gate valve cannot be used to adjust the total flow. It can apply ultra-low temperature pressure and ultra-high pressure and high temperature, and can be based on different materials of the valve. However, gate valves are generally not used in pipelines for transporting mortar and other substances. Knife gate valves can be used instead of general gate valve applications.

Gate valves can be used for high temperature and high pressure, and can be used for a variety of different media, but generally not used in pipelines for conveying mud and viscous fluids.

Advantage:

1. The fluid resistance is small.

2. It saves effort to open and close.

3. The flow direction of the medium is not restricted, does not disturb the flow, and does not reduce the pressure.

4. Simple shape, short structure length, good manufacturing technology and wide application range.

Generally, the use conditions or requirements require good sealing performance, high pressure, high pressure cut-off (big pressure difference), low pressure cut-off (small pressure difference), low noise, cavitation and vaporization, high temperature medium, low temperature (cryogenic), it is recommended to use gate valve . The gate valve can be used in the mud medium and the occasion where the leakage to the atmosphere is small. Try not to choose gate valves in media with throttling, adjustment, abrasion, rapid opening and closing, short operating force, and abrasiveness. Gate valves cannot be used in occasions with high opening and closing frequencies.
