Watts 0125344 Regulator

The Watts 0125344 (Series LF263A) is a high-performance lead-free water pressure regulator engineered for precision control in low-pressure commercial and industrial applications. This 1/4" NPT threaded valve is the direct 0335011 replacement, featuring a rugged forged lead-free brass body that meets stringent NSF/ANSI 61-G potable water requirements. Designed for versatile media, it efficiently manages both water and No. 2 fuel oil, making it a critical component for beverage dispensers, ice machines, and humidifiers. The Watts LF263A-1/4 utilizes an oversized orifice to maintain consistent downstream pressure between 1 and 25 PSI, factory-set at 10 PSI for immediate deployment. With a maximum working pressure of 300 PSI and a reinforced Buna-N diaphragm, this 3-way regulator provides the durability required by veteran contractors for reliable fluid pressure management in small-scale piping systems. The integrated 1/4" gauge port allows for simplified static pressure monitoring and easy tee-handle field adjustments.

• Lead-Free Compliance: Forged brass construction ensures the Watts 0125344 meets all safe drinking water standards for potable water service.
• Precise Low-Pressure Control: Optimized for a 1-25 PSI range with a reinforced Buna-N diaphragm for sensitive response in beverage and medical applications.
• Fuel Oil Compatibility: Rated to handle No. 2 fuel oil, increasing its utility in industrial heating and HVAC pressure regulation.
• Simplified Serviceability: The 3-way valve design with a low-pressure gauge port simplifies diagnostics and system maintenance.

Is the Watts 0125344 interchangeable with the older 0335011 model?
Yes, the 0125344 is the updated LF263A replacement for the legacy 0335011/263A-1/4, offering identical fitment with the added protection of lead-free materials.

Can I use this regulator for high-pressure residential mains?
The Watts LF263A 1/4 inch is specifically designed for low-pressure regulation (1-25 PSI). For whole-house high-pressure reduction, a Series LF25AUB or similar high-capacity valve is required.

Does this unit come with a pressure gauge?
The standard configuration includes a 1/4" NPT gauge port for pressure monitoring, though the physical gauge is typically sold separately to match the specific PSI range of your application.
