Description

Product Overview

The Watts LF25AUB-Z3 water pressure reducing valve is engineered to deliver precise pressure control for a wide range of applications. Built with a solid brass body and a high‑quality polymer seat, this valve ensures long‑term durability and resistance to corrosion. The NPT 3/4 inch female union connections provide a secure, leak‑free fit for standard pipe sizes, while the dual‑port design allows for easy integration into existing plumbing systems. With a maximum operating pressure of 300 psi and a pressure range of 25‑75 psi, the valve offers flexibility for both low‑pressure and moderate‑pressure environments. Its compact dimensions (6 × 3 × 6 inches) and lightweight construction (3.3 lb) make it suitable for tight spaces without sacrificing performance.

Usage

This valve is ideal for industrial facilities, commercial buildings, and residential properties where water pressure management is critical. It can be installed on main water lines to protect downstream equipment such as pumps, filters, and fixtures from pressure spikes that cause wear and leaks. The valve’s polymer seat is replaceable, allowing for easy maintenance and extended service life. Whether used in a manufacturing plant to safeguard sensitive machinery, in a hotel to ensure guest comfort, or in a home to reduce water waste, the LF25AUB‑Z3 delivers consistent performance.
