Zurn 34-600XLDM 3/4" Lead-Free Water Pressure Reducing Valve with Integral Strainer - Double Male Meter Connections

The Zurn Wilkins 34-600XLDM 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 600XLDM Pressure Reducing Valve with Double Male Meter Connections handles sandy, debris-laden water systems for meter setter applications, and is equipped with a sealed cage for below grade applications. It meets compliance with universal plumbing code. The stainless steel strainer includes a standard 20 mesh configuration and separate-access cover for simplified cleaning, while the bronze threaded bell and stainless steel adjustment bolt provide superior corrosion-resistance and speed access to the internals – together, cutting labor time up to 50%. Internal components of the 600XLDM utilize a balanced design, providing accurate downstream pressure without consideration of the incoming pressure.

Common Questions

What pressure is it set to out of the box?

34-600XLDM 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 - 34-600XLDM 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?

34-600XLDM 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.
