Watts 0009257 Valve

The Watts 0009257 is a trade-grade 3/4-inch LF25AUB-Z3 water pressure reducing valve engineered for rigorous commercial and residential applications. Designed to handle supply pressures up to 300 PSI, this lead-free pressure regulator utilizes a cast copper silicon alloy body to ensure compliance with potable water safety standards. It features a serviceable in-line design with a replaceable seat module and an integral stainless steel strainer, minimizing downtime during routine maintenance. The factory-set 50 PSI output is easily adjustable between 25 and 75 PSI, and the reinforced EPDM diaphragm supports high-temperature performance up to 160°F. Additionally, an integrated thermal expansion bypass prevents high-pressure spikes in closed systems. This unit is the direct replacement for 0069710 and LF25AUB-Z3-3/4 models, providing a seamless drop-in solution for contractors upgrading domestic water service entries.

• System Protection: Reduces incoming municipal pressure to protect downstream plumbing components and appliances.
• Corrosion Resistance: Features a Z3 sealed spring cage and stainless steel adjusting screws for durability in outdoor or pit installations.
• Thermal Management: Built-in bypass feature effectively manages pressure increases caused by thermal expansion.
• Efficient Servicing: The union inlet and modular internal components allow for full maintenance without removing the valve body from the piping.
• Lead-Free Reliability: Constructed from lead-free brass alloy to meet strict plumbing codes for consumable water systems.

How do I adjust the outlet pressure on the 25AUB-Z3?
Loosen the lock nut on the sealed spring cage and turn the adjusting bolt clockwise to increase downstream pressure or counterclockwise to decrease it. Verify the setting using a downstream pressure gauge.

Does this valve replace the older 25AUB models?
Yes, the 0009257 is the direct technical replacement for legacy 25AUB-3/4 and LF25AUB-Z3-3/4 series. It maintains the same 5-5/16 inch lay length for easy retrofitting.

Can this pressure reducing valve be installed in a pit?
This model is specifically designed for accessible outdoor or pit installations, thanks to its sealed spring cage which protects internal adjustment components from environmental debris and moisture.
