Watts Brass Tubular 3/4 LF25AUB-Z3 Pressure Reducing Valve

Product Description

The WATTS BRASS TUBULAR 3/4 LF25AUB-Z3 is a lead-free water pressure reducing valve designed to regulate incoming water pressure to a safe, controllable range within residential and light commercial plumbing systems. It accepts National Pipe Thread Female Union inlet and National Pipe Thread Female outlet connections, making it compatible with standard threaded pipe assemblies. The valve delivers an adjustable pressure range of 25-75 psi and incorporates a polymer seat for reliable sealing performance over extended service life. Licensed plumbers install this valve as part of service entry or branch protection applications where pressure regulation is required.

This valve is suited for residential water service lines and light commercial plumbing installations where incoming supply pressure must be reduced to protect downstream fixtures, appliances, and piping. It is a direct-threaded, union-style valve that fits into existing NPT pipe runs without special adapters. The lead-free construction meets applicable safe-drinking-water requirements, making it appropriate for potable water systems. Also referenced by ordering code 0960003.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the main water supply and relieve system pressure before removing any existing valve or making new connections. Apply thread sealant or PTFE tape to all NPT connections and tighten to a wrench-tight fit. After installation, open the supply slowly and verify output pressure with a gauge before returning the system to full service.
