Valves & Actuation
Manual Hayward Three-Way Ball Valves come standard with a two port “TW” ball allowing for three flow configurations within 180˚ of rotation. With the bottom port as the inlet, the flow can be directed to the right or left port, or shutoff. On manual or actuated valves, and optional “TP” ball allows flow through all ports at the same time or flow shutoff. True Union design makes these valves very easy to maintain by allowing for easy removal from a piping system without breaking downstream connections.
Hayward Y-Check Valves prevent reversal of flow in piping systems. They are ideal where backflow could potentially cause damage to pumps, filters or process equipment. Hayward Y-Check Valves operate without the need for any adjustments or settings. A plastic coil (not a spring) supports the disc inside the body. When the inlet flow stops, back pressure (a minimum of 2 psi is required) moves the disc with its elastomer o-ring onto a plastic seat - shutting off the flow.
