Spring Check Valves
Dayton spring check valves prevent backflow into wastewater lines, sump disposal lines, sewage lift stations and ejector systems. They are used with diaphragm, piston & metering pumps, and feature PVC / ductile iron construction for mechanical strength. They come integrated with Buna-N seals for excellent resistance to alcohols, petroleum-based oils & silicone greases; and are capable of withstanding liquid temperatures up to 180 degrees F.
