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.
