Hayward® AR Series PVC Air Release Valve

Hayward’s ¾” (socket or FNPT threaded) air release valve provides reliable tank venting and prevents tank overflow. Available with either a PVC or CPVC body with either EPDM or FPM seals, it’s true-union design simplifies installation and maintenance. The internal hollow polypropylene ball enables air to exit and rises to seal when the liquid level is high enough. Rated for pressures as high as 150 PSI, it closes at 0 PSI.
