Description
This DN20 brass water pressure reducing valve is designed to stabilize and limit hydraulic pressure in French residential, commercial, and small community installations. It incorporates a precise analog pressure gauge and a simple, reliable piston mechanism that is relatively insensitive to flow variations or minor impurities in the mains water. Its wide adjustment range (0.05 to 0.8 MPa) allows for fine-tuning the pressure to meet the specific needs of sensitive equipment (thermostatic mixing valves, electric water heaters, automatic irrigation systems, or reverse osmosis filters). The solid brass body ensures excellent mechanical strength and full compliance with French sanitary standards (NF D 30-001, NF EN 1717). Delivered ready to install, it can be fitted in minutes to any G¾” (DN20) threaded pipe, without requiring complex plumbing work or modifications to the existing network.
