Pool Check Valve with True Union Connections

This Hayward check valve uses a single-flow inline design with true union connections. The 3/4 inch FNPT by socket layout allows direct integration into PVC plumbing runs. Viton seals and seat material handle water temperatures from 40 to 140 degrees Fahrenheit. Rated for 235 psi at 70 degrees Fahrenheit with a 3 psi cracking pressure and 10 gpm full flow capacity.

PVC Body and Viton Seals for Chemical Resistance

The PVC body resists corrosion from pool chemicals and saltwater environments. Viton seals maintain elasticity across the rated temperature range. True union connections enable removal without cutting pipe, simplifying seasonal maintenance or valve replacement. Vertical mounting orientation ensures the internal mechanism seats properly under gravity and flow conditions.

Verify Pipe Size and Vertical Installation Space

Confirm the existing plumbing uses 3/4 inch pipe with compatible FNPT and socket fittings. The valve must be installed vertically to function correctly. Ensure system pressure does not exceed 235 psi at 70 degrees Fahrenheit. Steam service is not rated. Check that 10 gpm flow capacity matches the circulation pump output.

Questions about this item

What does the 3/4" FNPT x Socket connection mean for pipe compatibility?

The valve accepts a 3/4 inch female NPT thread on one end and a solvent-weld socket on the other, allowing direct connection to schedule 40 PVC pipe.

What clearance does the true-union body need for removal?

The inline true-union design requires enough axial space to unscrew both union nuts so the body can be lifted out for cleaning.

How is the Viton seat oriented during installation?

Install the valve vertically with flow entering the socket end so the internal check mechanism seats against the Viton seal at 3 psi cracking pressure.
