Backflow Prevention: Hayward Wafer Check Valves prevent reversal of flow in piping systems. They are ideal where backflow could potentially cause damage to pumps, filters, or process equipment.
Easy Installation: Hayward Wafer Check Valves are light weight and designed for easy installation. The valve’s wafer body slips between standard flanges and can be used in either vertical or horizontal operation**.
Reliable Operation: Hayward Wafer Check Valves operate without the need for any adjustments or settings. The valves plastic disc, with replaceable O-ring seals, is designed to provide a bubble-tight flow shutoff. When inlet flow stops, back pressure* moves the disc with its O-ring seal into the valves plastic body-shutting-off the flow.
Two Available Models: Hayward Wafer Check Valves are available in two types. A lower cost version without a disc spring is available for applications where it is not desirable for the process stream to come in contact with metals. A version with disc spring is recommended for pulsating flow and horizontal piping applications where faster disc closure is required to reduce the amount of backflow and possible water hammer.
