Watts 0009638 Reducing Valve
The Watts 0009638 (Model LFN55BM1) is a high-performance 1" NPT water pressure reducing valve engineered for demanding commercial and residential potable water applications. This lead-free brass water regulator serves as the direct replacement for LFX65B-1, offering superior flow characteristics and simplified maintenance. Specifically designed to drop high supply pressures to a manageable level, it protects downstream plumbing components from surge damage while significantly reducing water consumption.
Built with a lead-free copper silicon alloy body, the 0009638 features an integral stainless steel strainer and a thermoplastic seat cartridge, making it resilient against scale and debris. This adjustable pressure relief valve is factory-set at 50 psi but allows for field adjustment between 25 and 75 psi. The unit includes a thermal expansion bypass to manage back-pressure and a sealed spring cage, allowing for reliable operation in underground pits or outdoor enclosures where corrosion resistance is paramount.
Key Benefits for Contractors
- Direct Compatibility: Seamlessly replaces the discontinued LFX65B-1 without extensive repiping.
- In-Line Serviceability: Maintenance is streamlined via the removable seat cartridge and strainer, allowing repairs without pulling the valve body.
- System Protection: The thermal expansion bypass prevents high-pressure spikes from domestic water heaters, protecting pipes and fixtures.
- Rigorous Standards: Meets ASSE 1003 and CSA B356 requirements for lead-free installation in all 50 states.
- Installation Versatility: The 1-inch female NPT threads ensure a leak-proof connection for standard distribution lines.
Common Questions
What is the maximum incoming pressure for the Watts LFN55BM1?
This valve is rated for a maximum working pressure of 400 psi (27.6 bar) and can handle temperatures from 33°F to 180°F.
How do you adjust the pressure on a 1-inch Watts 0009638?
Loosen the lock nut and turn the corrosion-resistant adjusting screw clockwise to increase downstream pressure or counter-clockwise to decrease it.
Will this valve stop water hammer in my plumbing system?
While a water pressure regulator helps by lowering overall velocity, specific water hammer arrestors are recommended for severe hydraulic shock issues.
