Zurn 112-600XL3 1-1/2" Water Pressure Reducing Valve with Removable Integral Strainer and Venturi

The Zurn Wilkins 112-600XL3 is a 1-1/2" pressure reducing valve with single union FNPT connections. It reduces inlet pressure of up to 400 psi to an adjustable 15-75 psi downstream, factory set at 50 psi. It features a lead-free bronze body. Rated to 400 psi and up to 140°F.

The 600XL3 Pressure Reducing Valve with integral strainer is designed for residential and light commercial water lines, providing high-flow rate capacity and low-pressure falloff. The patented venturi technology ensures the valve delivers best-in-class flow performance. Constructed with an all-bronze body, stainless-steel stem, and cartridge internals, this valve offers superior corrosion resistance and increased product life, delivering exceptional value to the owner.

Common Questions

What pressure is it set to out of the box?

112-600XL3 ships factory set at 50 psi. The adjustable reduced-pressure range is 15 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 - 112-600XL3 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?

112-600XL3 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.
