Lead-Free Pressure Reducing Valve

The Watts LF25AUB-Z3 is a lead-free pressure reducing valve designed for potable water systems. It controls downstream pressure in residential and light commercial plumbing installations. The valve meets low-lead requirements for safe drinking water applications.

Adjustable 25-75 PSI Range

This valve replaces fixed-pressure or non-adjustable regulators where outlet pressure must be set between 25 and 75 PSI. The adjustment is worthwhile when supply pressure fluctuates or when fixtures require a specific pressure band. It upgrades older brass units that do not meet current lead-free standards.

1-Inch Connection Capacity

The 1-inch body handles flow rates typical for whole-house or small commercial services. It comfortably supplies multiple fixtures simultaneously while maintaining the set pressure. The valve reaches its limit when demand exceeds the flow capacity of the 1-inch port or when inlet pressure falls below the required minimum.
