Watts 0121325 Valve
The Watts 0121325 (Model 1XL-4-150) is a professional-grade 1/2 inch T&P relief valve engineered for critical temperature and pressure protection in water heater and storage tank applications. This ASME rated safety valve is designed to manage thermal expansion and prevent over-pressurization in systems with a maximum heat input of 15,000 BTU/hr. Featuring a 4 inch extension thermostat with a specialized thermo-bonded coating, the 1XL-4 ensures accurate sensing of tank temperatures, providing a 210°F temperature relief trip point. This specific unit is set for a 150 psi pressure relief threshold, matching standard requirements for most modern commercial and residential hot water tanks.
Constructed with a rugged bronze body and a stainless steel spring, this Watts temperature and pressure relief valve utilizes a non-mechanical seat-to-disc alignment for reliable reseating after discharge. For technicians in the field, the 1XL-4-150 offers an NPT threaded male inlet and NPT threaded female outlet, simplifying the installation process. Its CSA listed design meets the rigorous safety standards required for HVACR infrastructure. When replacing a water heater relief valve, ensure the BTU rating of the heater does not exceed the 15,000 BTU/hr capacity of this component.
Key Benefits
- Precision Sensing: The 4 inch extension thermostat ensures the probe reaches deep into the tank to monitor the peak water temperature accurately.
- Superior Durability: Features an all-bronze body and thermo-bonded coating on the thermostat to resist mineral buildup and corrosion.
- Standard Compliance: ASME rated and CSA listed for reliable performance under high-pressure conditions.
- Automatic Protection: Provides self-closing operation to protect against both excessive thermal expansion and pressure spikes.
Common Questions
What is the relief set point for this valve?
The Watts 0121325 is factory-set to trip at 150 psi and 210°F.
Can I use this on a heater larger than 15,000 BTU?
No. For safety and code compliance, the BTU discharge capacity of the T&P valve must exceed the BTU input rating of the water heater.
Is this model lead-free?
This specific MPN (0121325) refers to the standard bronze version; for potable water applications in specific jurisdictions, check for the Lead Free (LF) prefix requirement.
