vertical check valve
4 year agoSpring vertical non-return valve
Check valves are widely used in pipelines under various working conditions in the petroleum, chemical, pharmaceutical, and power industries. The spring vertical check valve is normally closed. Due to the pressure of the medium at the inlet end of the pipeline, it overcomes the spring resistance to open the valve.
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. Since the check valve adopts a spring to support the spool, it can be installed vertically or horizontally.
