Chemline Plastics ES Series spring check valves feature a PTFE-covered stainless-steel spring for positive closing, and a new disc design.

ES Series requires very low liquid head pressure to close, therefore it has more flexibility as to where valves may be placed in a piping system. It also has high corrosion resistance.

Spring check valves include:

  • Sizes: ½ to 3”;
  • Body: PVC;
  • Ends: socket, threaded, flanged, chemflare;
  • O-rings: EPDM or FKM.
