229818 - Miller 200 PSIG Pressure Relief Valve 1/4 NPT Male

Miller 229818 Relief Valve Overview

The Miller 229818 Relief Valve is a critical safety component designed for use in various welding systems and industrial applications. Engineered to open at a specific pressure threshold of 200 PSIG, this valve protects your equipment from the dangers of over-pressurization, which can lead to component failure or hazardous situations. As a genuine Miller Electric replacement part, it guarantees the reliability and performance standards expected from top-tier welding equipment manufacturers.

This valve features a standard 1/4-inch National Pipe Taper (NPT) male connection, making it compatible with a wide range of manifolds, tanks, and fluid lines commonly found in welding coolant systems or gas delivery setups. The precision-machined threads ensure a tight, leak-free seal when installed with appropriate thread sealant. Its compact design allows it to fit into tight spaces within machine housings without obstructing other components.

Maintenance and repair professionals rely on OEM parts like the 229818 to ensure that safety systems function exactly as the original engineers intended. Using non-standard or generic relief valves can result in incorrect pressure release points, potentially compromising the integrity of the machine. Whether you are repairing a TIG cooler, a plasma cutter air line, or a specific Miller power source, verifying the part number and pressure rating is essential for a successful repair.

Installation is straightforward for qualified technicians. The valve is designed for durability and long service life, resisting corrosion and wear typical of industrial environments. By maintaining the correct pressure balance within your system, this relief valve helps extend the lifespan of pumps, hoses, and seals, ultimately reducing downtime and maintenance costs.
