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.
