Y34-311 - Miller Smith 1/4 MNPT Brass Needle Valve

Reliable Gas Control for Welding Setups

Keep your welding operations running smoothly with the Miller Smith Y34-311 Needle Valve. As a professional welder or fabricator, you know that consistent gas flow is the backbone of a quality weld. Whether you are managing shielding gas for MIG and TIG processes or controlling fuel gas in an oxy-fuel setup, having a reliable valve to regulate flow is essential. This genuine Miller Smith part is designed to replace worn-out valves on manifolds, regulators, and custom gas distribution panels, ensuring you maintain precise control over your equipment.

The Y34-311 features 1/4-inch MNPT threads, making it a versatile solution for many standard connections found in welding shops. The male pipe threads allow for direct connection into manifolds, couplers, or other female-threaded fittings, creating a secure and leak-proof seal. Leaks in a gas system not only waste expensive consumables but can also create safety hazards and lead to porosity in welds. Installing a high-quality brass needle valve like this one helps eliminate those risks by providing a positive shut-off and accurate flow metering capability.

Durability is key in a shop environment. This valve is built from solid brass, which stands up to the daily wear and tear of industrial use. It resists rust and corrosion, ensuring the handle turns smoothly even after months of service. The needle design allows for fine-tuning, so you can dial in the exact amount of flow needed for your specific application, rather than just having an on/off switch. This is particularly useful when building custom purge lines or setting up secondary flow paths for specialized welding tasks.

Don't let a faulty valve compromise your work quality. The Miller Smith Y34-311 is an easy-to-install upgrade or replacement that restores the precision your equipment was designed to deliver. It is compatible with a variety of gases commonly used in the industry, making it a valuable addition to your spare parts inventory. Trust in Miller's reputation for quality to keep your gas delivery systems safe, efficient, and reliable.
