Product Description

The WATTS Temperature and Pressure Relief Valve is a Non-Code Temperature & Pressure Relief Valve with a Copper Silicon Alloy body. It features a 1/2 in x 1/2 in MNPT x FNPT connection size (MPN 1/2 LF1XL 150-210).

Frequently Asked Questions

What is the WATTS Temperature and Pressure Relief Valve used for?

The WATTS Temperature and Pressure Relief Valve is used to protect water heaters and storage tanks from excessive temperature or pressure. It automatically opens to discharge water when internal conditions exceed safe limits, preventing equipment damage or failure. This non-code valve is suitable for residential and light commercial applications.

What are the specifications of the WATTS 1/2 LF1XL 150-210 valve?

This WATTS valve has a Copper Silicon Alloy body and features a 1/2 in MNPT x 1/2 in FNPT connection size. The manufacturer part number is 1/2 LF1XL 150-210. It is classified as a Non-Code Temperature & Pressure Relief Valve, designed for standard water heater protection without code compliance requirements.

Where to buy the WATTS 1/2 LF1XL 150-210 valve worldwide?

You can source the WATTS 1/2 LF1XL 150-210 valve from 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine WATTS components for international procurement needs.

How to install a WATTS temperature and pressure relief valve?

Install the WATTS valve directly into the water heater tank opening using thread sealant on the male threads. Ensure the discharge pipe slopes downward and terminates within 6 inches of the floor. Do not cap or plug the outlet. Follow local plumbing codes and the manufacturer's instructions for safe operation.

Used in

Common applications for Watts
Industrial burner gas safety systems — Watts HF2000 filters with GF-series seal kits maintain clean, regulated gas supply to burner pilot and main flame controls
Commercial heating and boiler installations — Modular filter assemblies support preventive maintenance and component replacement without full system shutdown
Process gas delivery pipelines — DN25 through DN125 filter bodies accommodate varying flow rates and inlet pressures across manufacturing and chemical processes
Gas pressure regulation benches — Multi-stage Watts filter platforms integrate with pressure reducers and safety shutoff valves in test and calibration environments
Equipment retrofit and upgrade projects — Available connection sizes and seal kits enable adaptation of newer Watts components into legacy gas control systems
Planned maintenance and spare-parts inventory — Filter seal kits allow facilities to stock consumables in advance, reducing downtime during scheduled gas system servicing
