Zurn 34-625XLSULU 3/4" Lead-Free Water Pressure Reducing Valve with Integral Strainer - Competitor Replacement Length

The Zurn Wilkins 34-625XLSULU is a 3/4" lead-free pressure reducing valve with FNPT connections. It reduces inlet pressure of up to 300 psi to an adjustable 25-75 psi downstream, factory set at 50 psi. It features a lead-free bronze body. Rated to 300 psi and up to 140°F. This model is certified lead-free for potable-water installations.

The 625XL Pressure Reducing Valve is a superior drop-in replacement solution for single union competitor models, reducing installation costs in both commercial and residential applications. The 625XL eliminates the need for re-piping, saving you valuable time, labor, and materials. It includes the same corrosion-resistant, bronze threaded bell and integral stainless steel strainer as the 600XL, which speeds up access to internals for easy cleaning. The fiber union gasket ensures rapid installation. Its high-flow capacity is ideal for sandy, debris-laden systems that may require frequent cleaning.

Common Questions

What pressure is it set to out of the box?

34-625XLSULU ships factory set at 50 psi. The adjustable reduced-pressure range is 25 to 75 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 - 34-625XLSULU 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?

34-625XLSULU 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.
