JIS 10K Lift Check Valve can also be called a spring check valve. There is a spring inside to reset it. Due to the pressure of the medium at the inlet end of the pipeline, the valve can be opened by overcoming the resistance of the spring. When the medium pressure at the inlet end is lower than that at the outlet end, the spring pushes the valve core to the valve seat to close the valve, preventing the medium from flowing back, so it acts as a check.
JIS 10K flange spring check valve
Its internal structure is very different from the swing check valve
JIS 10K flange Lift Check Valve
The valve can be installed vertically or horizontally due to the spring-supported valve core.Because the horizontal installation of the internal valve stem will be affected by the downward gravity, the valve core will be unevenly stressed during use, and the main installation method is recommended to be installed vertically.
