    Reliable Pressure Relief
    Hayward Pressure Relief Valves protect piping system components from damage due to overpressurization. The valves work by sensing system pressure. When the system pressure exceeds the set pressure, the force of the excess pressure moves the valve piston off its seat to relieve the excess pressure and diverts some of the flow out the discharge port.

  • PR Series

    Reliable Pressure Regulation
    Hayward Pressure Regulators prevent downstream pressure from exceeding a preset pressure. When the upstream pressure increases beyond the set pressure of the regulator, the regulator prevents the downstream pressure from exceeding the set pressure.

  • LC Series

    For on/off, restricted flow or sampling applications, the Hayward StopCock is easily adaptable to any piping connection. Furnished with the valve is a 1/4" NPT female pipe thread, 1/4" NPT male pipe thread and hose barb end connectors for 1/4" through 7/16" I.D. tubing. These allow the valve to be fitted with up to six different end connection combinations. Simply attach the end connections you need – they are all supplied with each valve.

  • NVA Family

    Needle Valves are used for accurate metering of fluids. Turning the thumbwheel moves a tapered piston into the PTFE seat to control the flow down to a few drops per minute. Precision-molded, fine-pitched stem threads permit this very fine metering flow control.

  • AV Series

    Hayward Angle Valves are used in tight spaces where a 90° change in flow direction is needed and there is insufficient room for extra fittings. Since they are globe valves, they are ideal for sampling and throttling applications.

  • AR Series

    Tank, Container and Vessel Protection
    Emptying or filling a closed tank requires that it be vented to allow the passage of air into or out of the tank in order to prevent damage to the tank. This is the function of Hayward’s True Union Air Release Valve. It prevents overflow of the process fluid as a tank is being filled while allowing air to escape, minimizing the risk of the tank expanding as the result of compressing trapped air.

  • DAB Series PVC

    Hayward all-plastic diaphragm valves are engineered to provide superior handling of difficult media such as corrosive fluids, abrasives and slurries. They can also be used for high purity and sanitary applications.
