ES Series spring check valve
By MRO Staffspring check valve
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.
