Lead Free 3/4 Pressure Relief Valve Merrill – No Lead Brass 100 PSI

Description

Product Overview

The Merrill PRVNL75100 is a lead‑free pressure relief valve designed specifically for cold‑water plumbing applications. Crafted from premium no‑lead brass and equipped with stainless‑steel control springs, this valve provides reliable protection against pressure spikes up to 100 PSI. It complies with NSF/ANSI‑61 and NSF/ANSI‑372 standards, guaranteeing that the valve will not introduce contaminants into drinking water. The valve features a 3/4″ male NPT inlet and a 1/2″ female NPT outlet, making it compatible with standard pipe fittings used in residential, commercial, and light‑industrial water systems. Its compact dimensions (1.45 x 1.05 x 2.47 inches) and lightweight design (6.4 oz) allow for easy installation in tight spaces while maintaining robust performance.

Usage

This valve is intended for cold‑water distribution networks, such as domestic water lines, irrigation systems, and low‑temperature industrial circuits. It is not suitable for water‑heater applications or hot‑water systems. The valve’s no‑lead construction makes it an excellent choice for potable‑water installations where health and safety are paramount. Install the valve on a 3/4″ NPT male thread of the supply line and connect the 1/2″ NPT female thread to the downstream equipment. Once installed, the valve automatically releases excess pressure, preventing damage to pipes, fixtures, and appliances. Its reliable operation is essential for facilities that require consistent water pressure regulation, including schools, hospitals, and multi‑unit residential buildings.
