1-1/2" PVC True Union Swing Check Valve

This Dayton 4RG90 check valve uses a true-union socket design for simple installation and removal in drain and waste-water lines. The PVC body resists corrosion in general-purpose plumbing applications. It mounts vertically and measures 8 inches long by 3 5/32 inches wide and high.

125 psi maximum water pressure rating

The single specification that determines suitability is the 125 psi maximum water-pressure rating; the valve is not rated for steam. Systems that exceed this pressure require a different valve. Verify your line pressure before specifying this part.

True union socket ends simplify maintenance

The true-union socket connections let the valve body be removed without cutting pipe, reducing downtime during inspection or cleaning. No additional gaskets or tools are bundled, so installers supply their own solvent cement and pipe.

Questions about this item

How does the 125 psi pressure rating affect everyday plumbing use?

The valve is rated for 125 psi cold water, so it handles typical residential supply pressure without leaking or premature wear.

What does the socket connection mean for installation?

The socket ends accept 1-1/2 inch PVC pipe that is solvent-cemented in place, creating a permanent leak-free joint.

What clearance is needed to fit the 8 inch true-union body?

The valve measures 8 inches long and 3 5/32 inches wide, so allow at least that space plus room to tighten the union nuts.
