Resilient Seated Check Valve for Reliable Flow Control
If you want cost-effective backflow protection for our piping systems, look at what this resilient seated check valve has to offer. It’s the only fully elastomer-lined insert check valve available. The ductile iron valve body is completely isolated from line media which can extend the service life of the Series 800 in most applications and makes it an especially economical alternative in applications which would otherwise require check valves made of expensive alloys.
Ductile Iron Backup Ring for High-Performance Resilient Seated Check Valves
This Backup Ring is made of Ductile Iron, and machined with high precision machining equipment. It has good physical and mechanical features. Afterwards the back-up ring will be lined with rubber material to form a 800S Check Valve seat. It gives enough support of the valve seat and guarantees the long-lasting use.
Furthermore, the DI Backup Ring pays well in economy for 800S Check Valve.
