Product Description

stainless steel  check valve

Normally in the closed state, the valve opens due to the pressure of the medium at the inlet end of the pipeline, 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. Because this valve adopts a spring to support the spool, it can be installed vertically or horizontally.
