Pressure Relief Valve Merrill 1/2″ Brass No Lead Relief Valve PRVNL50

Description

Product Overview

The Merrill PRVNL50 is a precision‑engineered pressure relief valve designed for industrial and scientific applications where safety and reliability are paramount. Constructed from lead‑free brass, the valve offers excellent corrosion resistance and durability, ensuring a long service life even in demanding environments. Its compact 1/2 inch size makes it easy to integrate into existing piping systems without sacrificing performance. The valve is certified to meet IAMPO, NSF/ANSI 372, and AB 1953 standards, providing confidence that it complies with stringent safety and material specifications.

Key specifications include a maximum operating pressure of 75 psi, a single port configuration, and a stainless steel control spring that delivers consistent opening and closing action. The inlet connection utilizes a National Pipe Tapered (NPT) male thread, while the outlet features a Female Pipe Thread (FPT) to accommodate a wide range of fittings. With a lightweight design of just 5.6 ounces and package dimensions of 8.07 x 2.52 x 1.14 inches, the valve is both easy to handle and install.

Usage

This valve is ideally suited for protecting pneumatic and hydraulic circuits from over‑pressure conditions that could otherwise cause equipment damage or safety hazards. It is commonly used in cold‑water systems, air compressors, and other applications where water heating is not involved. The 1/2 inch line connection allows for seamless integration with standard tubing and pipe sizes, making it a versatile choice for both new installations and retrofits.

Because the valve is made from lead‑free brass and features a stainless steel control spring, it is safe for use in environments where contamination must be minimized, such as food processing plants, medical equipment, and clean‑room facilities. The valve’s reliable performance under a maximum pressure of 75 psi ensures that it will activate precisely when pressure thresholds are exceeded, protecting downstream components and maintaining system integrity.
