Watts 0009396 Valve
The Watts 0009396, specifically the 1 1/2 inch LF25AUB-Z3, is a heavy-duty water pressure reducing valve designed for commercial and industrial applications requiring precise downstream regulation. This lead-free brass water regulator features a reinforced diaphragm and a high-capacity bypass mechanism to handle thermal expansion effectively. With its union threaded inlet and NPT outlet, the 1-1/2" LF25AUB-Z3 maintains a consistent delivery pressure despite fluctuating municipal supply. The adjustable pressure range of 25 to 75 psi allows technicians to dial in specific building requirements, while the integral stainless steel strainer protects the valve seat from debris and scale. Engineered for performance in potable water systems, this valve complies with ASSE 1003 and CSA B356 standards. Its modular design allows for in-line maintenance, ensuring long-term reliability in high-flow plumbing and HVAC loops where 1-1/2 inch LF25AUB-BSP-Z3 specifications are required for system stabilization.
Key Benefits for Technicians
- Lead-Free Construction: Complies with low-lead plumbing codes for safe potable water distribution.
- Internal Bypass: Effectively manages thermal expansion pressure, reducing the need for additional expansion tanks in specific configurations.
- Serviceable Design: Features a replaceable disc and strainer for rapid field maintenance without removing the valve body.
- Durable Diaphragm: High-temperature EPDM reinforced diaphragm provides reliable performance in varying thermal environments.
- Precise Regulation: Delivers high-volume flow with minimal pressure fall-off during peak demand periods.
Common Installation & Performance Questions
What is the maximum inlet pressure for the Watts LF25AUB-Z3?
This valve is rated for a maximum supply pressure of 300 psi, though regular operating ranges typically sit below this limit for optimal component life.
How do I adjust the output pressure on a 1-1/2 inch Watts regulator?
Loosen the lock nut on the adjustment bolt and turn the bolt clockwise to increase downstream pressure or counter-clockwise to decrease it. Always use a calibrated gauge to verify settings.
Is the 0009396 model compatible with hot water lines?
Yes, the LF25AUB-Z3 series is rated for temperatures up to 160°F (71°C), making it suitable for both cold and hot domestic water service.
