Product Description
Wafer Knife Gate Valve with Double-sided Flange and Gearbox
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.
