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

Precision Flow Control with Miller Smith Engineering

The Miller Smith Y34-311 Needle Valve is a specialized component designed for the rigorous demands of industrial gas and fluid management. Engineered with precision, this valve serves as a critical control point in various piping and manifold configurations, allowing operators to finely tune flow rates with accuracy. The unit features a 1/4-inch Male National Pipe Thread (MNPT) on both the inlet and outlet, ensuring broad compatibility with standard industrial fittings and piping systems. The use of NPT threading provides a tight, leak-resistant seal essential for maintaining system integrity under pressure.

Constructed from high-quality brass, the Y34-311 offers excellent durability and resistance to corrosion, making it suitable for a wide range of environments. Brass is the material of choice for many gas applications due to its non-sparking properties and resilience against environmental wear. The needle mechanism within the valve is designed to provide linear flow characteristics, enabling gradual adjustment of the media passing through. This is particularly important in applications where sudden surges in pressure or flow could damage downstream equipment or compromise process stability.

In the context of MRO (Maintenance, Repair, and Operations), having reliable isolation and control valves is paramount. The Y34-311 is often utilized in gas mixing systems, test benches, and custom fabrication setups where precise metering is required. Its compact footprint allows for installation in tight spaces without sacrificing accessibility for adjustment. Whether used for inert gases, compressed air, or other compatible fluids, this Miller Smith valve delivers the performance expected from a leading manufacturer in the welding and industrial sector.

Integration of this valve into existing systems is straightforward due to its standard dimensions. It serves as an ideal replacement for worn or seized valves in older equipment, restoring functionality and safety. The robust stem and handle assembly are built to withstand frequent adjustments, ensuring a long service life even in active production environments.
