Hayward® Y check valves Hayward’s Y check valves are available in ½” to 4″ sizes in PVC, CPVC and PVDF

Y check valves are an improved version of a spring loaded check valve and enable inspection and replacement of valve components without needed to remove the valve body from the system. This is especially important for glued socket connections but equally convenient for check valves having true union connections.

Our Y check valves are constructed entirely of non-alloy materials with the body, piston and spring made of either PVC or CPVC and the o-ring seal either EPDM or FPM. As with all non-alloy valves, Y check valves are only designed for liquid applications and NOT air or gases. Non-liquids have a substantial amount of stored energy even at low pressures and thus failure of the valve body could result in an explosion of PVC, CPVC or PVDF shards.

These can be used in either horizontal or vertical piping as long as the capped spring chamber is facing upwards and you’ll note the cracking pressure is slightly higher than the 1.5 PSI cracking pressure for ball check valves. Even though there is an internal spring to ensure positive seating of the plunger to the seat, at least 2 PSI of back pressure is required to ensure a good seal. The full flow design results in a minimal differential pressure.

The PVC and CPVC Y check valves have either a socket, threaded or ANSI flanged inlet and outlet connection. The PVDF version is offered in 1/2″, 3/4″ and 1″ size with either IPS socket fusion or FNPT (threaded) connections. Since PVC and CPVC Y check valves are not suitable for temperatures below 34F, PVDF is used for both liquids not compatible with PVC/CPVC as well as temperatures as low as 10F.
