Check Valve

Check Valves are widely used in high pressure lines to control one-way flow and prevent fluid from flowing back to the pump, thus to protect pipeline safety.

Jereh Check Valves include top-entry check valves, in-line flapper check valves and dart check valves. Flappers of top-entry and in-line flapper check valves which are mainly used in fluid condition adopt complete coating design, increasing service life. Dart check valves are mainly used in air condition.

Special repair kit is available for quick and inline maintenance.
