A check valve allows flow in one direction and automatically closes to stop reverse flow, protecting a line against backflow and back-siphonage. These check valves are stocked with solder (Cxc) and threaded (Ips) connections across common sizes, plus a corrosion-proof PVC option, for water and general plumbing service.
Key Features:
- One-Way Flow -- Opens under forward flow and closes to prevent reverse flow and back-siphonage.
- Solder, Threaded, or PVC -- Sweat solder-cup (Cxc), threaded (Ips), and PVC options to match the line.
- Common Size Range -- Metal valves stocked from 1/2 in. through 2 in.
- Automatic Operation -- Internal check acts on flow direction with no external control.
- Backflow Protection -- Guards potable and equipment lines against contamination from reverse flow.
Where to Use:
- Building maintenance -- Preventing backflow on water supply, pump, and equipment lines
- Rough plumbing -- Installing one-way flow protection on new runs
- Code compliance -- Backflow prevention where required by local plumbing code
