Watts 0009465 Valve

For high-capacity commercial or residential applications requiring precise pressure control, the Watts 0009465 (Series LF25AUB-Z3) is the industry-standard 2-inch lead free water pressure reducing valve. This unit is the direct updated version for legacy models including 0070330, 0070336, 25AUB-2, and LF25AUB-Z3-2. Engineered with a lead free copper silicon alloy body, it provides superior durability and compliance with stringent potable water regulations. The 2" NPT threaded female union inlet and NPT female outlet allow for straightforward integration into existing iron pipe size (IPS) systems.

This pressure regulator is designed for a maximum working pressure of 300 PSI and features an adjustable reduced pressure range of 25 to 75 PSI, factory-set at 50 PSI. Technicians will appreciate the replaceable seat module and integral stainless steel strainer, both of which are serviceable in-line without removing the valve body. The Z3 sealed spring cage and stainless steel adjustment screws allow for reliable performance in outdoor or pit installations. Additionally, the built-in bypass feature effectively manages thermal expansion pressure, protecting downstream components from spikes caused by water heating in closed systems.

• Universal Compatibility: Serves as a drop-in replacement for the Watts 25AUB series and LF25AUBZ3-2, ensuring minimal downtime during retrofits.
• Enhanced Durability: Features a high-temperature resistant reinforced EPDM diaphragm suitable for water temperatures from 33°F to 180°F.
• Simplified Maintenance: The union inlet connection and top-entry design facilitate rapid cleaning of the stainless steel strainer and seat replacement.
• Corrosion Resistance: Equipped with a sealed spring cage and stainless steel cage screws specifically for harsh environments.

Is the 0009465 compatible with older 25AUB-Z3-2 units?
Yes, the Watts 0009465 is the designated updated replacement for the LF25AUB-Z3-2 and the original 25AUB-2. It maintains the same 2-inch NPT technical footprint for easy swap-outs.

Can this PRV be installed in a pit or outdoor environment?
This model utilizes the Z3 spring cage, which is specifically sealed and uses stainless steel screws to resist corrosion in accessible outdoor or underground pit applications.

Does this valve handle thermal expansion?
The LF25AUB-Z3 includes an integrated bypass feature that allows water to flow back into the main supply when downstream pressure exceeds supply pressure due to thermal expansion.
