Watts 0009329 Valve

The Watts 0009329 is a technical-grade 1" LF25AUB-HP-Z3 water pressure reducing valve engineered specifically for high-pressure commercial and residential plumbing systems. This veteran-preferred PRV serves as the direct lead-free replacement for legacy models 0070441, 0070430, and 25AUB-HP-Z3-1. Designed with a lead-free copper silicon alloy body, it manages incoming water pressure in a high-reduction range of 75 to 125 psi, with a factory standard setting of 90 psi. The unit features an integrated bypass feature to handle thermal expansion and a sealed spring cage with stainless steel screws, making it ideal for harsh environments or pit installations. Its modular design includes a replaceable seat module and an integral stainless steel strainer, allowing for full in-line serviceability without breaking the pipe connections. This 1-inch FNPT union inlet x FNPT outlet assembly ensures high-capacity flow while protecting downstream fixtures from the stresses of high-pressure utility mains.

Key Performance Benefits

• High-Pressure Regulation: Optimized for high-range reduction (75-125 psi) to safeguard sensitive appliances and piping.
• Maintenance Efficiency: Features a replaceable seat module and strainer that are serviceable in-line, reducing contractor labor time.
• Lead-Free Compliance: Constructed from lead-free materials to meet stringent potable water safety standards.
• Thermal Expansion Control: Built-in bypass feature prevents downstream pressure spikes caused by water heater cycling.
• Robust Construction: Equipped with a sealed spring cage and corrosion-resistant stainless steel trim for maximum durability in damp locations.

Common Questions

Can I adjust this valve to a lower residential pressure like 50 psi?
No. The Watts 0009329 is a high-pressure ("HP") model specifically designed for a 75-125 psi range. For standard 50 psi applications, the standard Watts LF25AUB-Z3 series should be used instead.

How do I resolve pressure creeping at night?
Pressure creep is typically caused by debris on the seat or thermal expansion. Clean the integral stainless steel strainer and check your expansion tank. If the seat is damaged, the replaceable seat module allows for a quick internal rebuild.

Is the union nut included with this model?
Yes, this specific part number includes the FNPT threaded female union inlet and the standard female NPT outlet for a simplified installation process.
