Metal Sealing Gate Valve

DN: 50-300 mm | PN: 25-40 bar

Gate valves are used in all water supply facilities, including raw drinking water and non-corrosive fluids up to 80 ° C. In the open state, these valves cause little turbulence compared to other shut-off valves in the path, and also the pressure drop caused by them is not significant, and in the completely closed state, it can prevent the passage of flow well. The use of gate valves in transmission lines as a flow controller is not allowed and must be used in fully open or fully closed state.
