How to install the WATTS 1/2 LF25AUB-HP-Z3 water pressure regulator?

Install the WATTS 1/2 LF25AUB-HP-Z3 in the main water line after the shutoff valve, with the arrow on the body pointing in the flow direction. Use thread sealant on the FIP connections and ensure the regulator is accessible for adjustment. Set outlet pressure between 75 psi and 125 psi using the adjustment screw, then check for leaks.

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
