Product Description
The gate valve is a gate with opening and closing parts.
The movement direction of the gate is perpendicular to that of the fluid.Gate valves can only be fully opened and closed.
They are mainly used as cutting off media in pipelines and not as regulating flow rate.
It can be used in low temperature and low pressure, high temperature and high pressure, and can be used in different media according to the different material of the valve.

1. Fluid resistance is small.
2. Opening and closing require less external force.
3. The flow direction of the medium is unrestricted.
4. When fully open, the sealing surface is less eroded by the working medium than the globe valve.
5. Shape is relatively simple and its casting technology is good.
