Watts 0388805 Regulator
The Watts 0388805 (Model T1450F) is a precision-engineered 1/2 inch dual control regulator and relief valve designed for integrated pressure management in closed-loop hydronic heating systems. As a veteran-grade boiler feed valve, it features an iron and bronze body construction optimized for high-capacity performance. This pressure reducing valve combination simplifies boiler pressure regulation by automatically filling the system and maintaining constant operational pressure while providing essential make-up water during minor leaks. The T1450F is equipped with a unique union threaded inlet for rapid installation and a built-in purge lever, facilitating manual system air removal. A stainless steel strainer prevents sediment from fouling the valve disc, and the integrated diaphragm relief valve is factory-calibrated to discharge at 30 PSI, ensuring the structural integrity of the boiler and distribution piping. Standard setting for the regulator is 15 PSI with an adjustable range of 10-25 PSI, suitable for maintaining pressure at 212°F maximum temperatures.
Key Benefits for the Contractor- Dual-Function Integration: Combines a high-capacity pressure regulator and a safety relief valve into a single, compact unitized design.
- Serviceability: Features an accessible internal design and a built-in manual purge lever for streamlined system startups.
- Debris Protection: The integral stainless steel strainer protects the internal seating surfaces from pipe scale and system particulates.
- Versatile Inlet Connection: Utilizing a 1/2" threaded union, the 0388805 reduces labor time during swaps and installs.
- Leak Protection: Provides reliable make-up water to compensate for system pressure loss, preventing air ingress in residential or commercial systems.
Is the Watts 0388805 suitable for potable water?
No, this unit is designed strictly for non-potable hydronic heating applications due to its iron body construction and non-lead-free materials.
What is the factory pressure setting for this dual control valve?
The regulator is factory set to 15 PSI, while the safety relief valve is set at 30 PSI (206.9 kPa) to protect the boiler system.
How do I bleed air from the system using this valve?
Use the manual purge lever located on the regulator side to bypass the standard setting and push water through the zones for faster air evacuation.
