Check Valves
Backflow Prevention
Hayward True Union Ball Check Valves prevent reversal of flow in piping systems. They are ideal where backflow could potentially cause damage to pumps, filters or process equipment.
True Union Design
Sizes 1/2” to 4” feature a true union design. This allows for easy removal from a piping system without breaking down piping connections. Pressure rating of 150 psi @ 73°F (non-shock).
PVC Utility Swing Check Valves are designed for horizontal installations, but may be installed in up-flow vertical position. Check valves must be installed with the valve’s FLOW arrow pointing in the direction of the flow. Flow velocity should not exceed 5 feet per second.
• Pressure Rating - 150 psi @ 73°F • Maximum Service Temperature - 140°F • EPDM seal for positive sealing
• Flow velocity < 5 ft./sec.
