Watts 0009330 Valve

The Watts 0009330 (Model 1" LF25AUB-LP-Z3) is a heavy-duty, lead-free water pressure reducing valve engineered for low-pressure applications. Designed to handle supply pressures up to 300 PSI, it features an adjustable reduced pressure range of 10 to 35 PSI, factory-set at 30 PSI for precise downstream control. This 1-inch NPT pressure regulator utilizes a lead-free copper silicon alloy body and a replaceable seat module, allowing for efficient in-line serviceability without total system teardown. The integral thermal expansion bypass prevents high-pressure spikes in closed loops, protecting sensitive plumbing components. A built-in stainless steel strainer filters out debris, while the sealed spring cage and stainless steel screws ensure durability in demanding environments. This unit serves as a direct replacement for legacy models including 0068532, 0079110, 25AUB-LP-1, and 25AUBLP-1, ensuring seamless HVAC performance and code compliance for commercial and residential installations.

• Precise Pressure Control: Adjustable 10-35 PSI range specifically designed for low-pressure system requirements.
• Efficient Maintenance: Features a fully replaceable seat module and a removable stainless steel strainer for quick in-line servicing.
• System Protection: Integrated bypass feature manages thermal expansion pressure to prevent plumbing failure.
• Lead-Free Compliance: Constructed from lead-free copper silicon alloy to meet federal safety standards for potable water.
• Retrofit Ready: Standard 1-inch NPT union inlet by NPT female outlet configuration simplifies replacement of older 25AUB units.

What is the maximum inlet pressure for the LF25AUB-LP-Z3?
This valve is rated for a maximum working pressure of 300 PSI (20.7 bar).

Does this valve come with a thermal expansion bypass?
Yes, the 0009330 includes a standard bypass feature that allows water to flow back into the main when downstream pressure exceeds supply pressure due to thermal expansion.

Can I service this regulator without removing it from the piping?
Yes, the design allows for easy maintenance with a replaceable seat module that can be accessed while the valve remains in-line.
