True Union Spring Loaded Check Valves
(1/2" to 4", PVC and Corzan® CPVC)

Backflow Prevention: Cepex by Hayward True Union Spring Loaded Check Valves prevent reversal of flow in piping systems. They are ideal where backflow could potentially cause damage to pumps, filters, or process equipment.
Automatic Operation: The valves operate without the need for any adjustments or settings. Line pressure moves the plastic cone off the elastomer seat, opening the valve. When the inlet flow stops, a spring moves the cone back onto the seat, stopping the flow.The spring is constructed from Inox. Steel ASI 302.
True Union Design: All True Union Spring Loaded Spring Check Valves feature a true union design. This allows for easy removal from a piping system without breaking down piping connections. Just unscrew the two assembly nuts and lift the valve body out of the line.
Cost Effective Design: Cepex by Hayward True Union Spring Loaded Check Valves are the valves of choice for cost sensitive applications the require a full featured, no compromise valve.
