Common Questions

What pressure is it set to out of the box?

114-NR3XLHRSC ships factory set at 50 psi. The adjustable reduced-pressure range is 15 to 125 psi, so you can dial the outlet anywhere in that band on site with the adjusting bolt - loosen the locknut, turn to raise or lower pressure, retighten and verify with a downstream gauge.

Does it include a strainer?

Yes - 114-NR3XLHRSC has an integral strainer built into the body, so a separate inline strainer ahead of it is not required. It is accessible for cleaning without removing the valve from the line.

Does it have a built-in bypass for thermal expansion, or do I still need an expansion tank?

114-NR3XLHRSC includes an integral thermal-expansion bypass that relieves excess downstream pressure back toward the supply when street pressure is lower. It is not a substitute for a properly sized expansion tank where your local code requires one - the bypass only relieves back to the street when street pressure is lower than the closed-system pressure.

Can this be installed in a pit or vault?

Yes - 114-NR3XLHRSC ships with the sealed bell housing and stainless steel adjustment screw needed for below-grade, pit, vault or indoor-enclosed installation. Zurn's own installation note requires this option whenever the valve is not in open, ventilated space.
