851-B - Western Enterprises 1/4 Inch Brass Needle Valve Male NPT

Precision Flow Control with Western Enterprises 851-B

The Western Enterprises 851-B Brass Needle Valve is a high-quality component designed for professionals who demand precision and reliability in their gas and fluid systems. Manufactured by Western Enterprises, a leader in gas control products, this valve is engineered to provide accurate flow metering in a compact and durable package. The unit features a 1/4-inch NPT Male connection on both the inlet and outlet, making it highly compatible with standard piping and instrumentation setups found in industrial environments.

Constructed from high-grade brass, the 851-B offers excellent resistance to corrosion and wear, ensuring a long service life even in demanding conditions. The brass body is machined to tight tolerances, providing a leak-tight seal and smooth operation. The core of this valve is its needle plunger mechanism, which allows for fine adjustments to the flow rate. Unlike ball valves that are typically designed for on/off control, the needle valve design enables the operator to gradually open or restrict the passage, making it ideal for applications where specific pressure or flow rates must be maintained.

Safety and compliance are paramount in industrial gas applications, and the 851-B meets these needs with its CSA certification. This approval signifies that the valve has undergone rigorous testing to meet safety standards, giving users peace of mind when integrating it into their systems. Whether used in laboratory instrumentation, pneumatic control panels, or gas distribution manifolds, this valve delivers consistent performance. Its pressure rating of up to 200 PSI covers a wide range of low-to-medium pressure applications, making it a versatile tool in any maintenance or engineering inventory.

Installation is straightforward thanks to the standard tapered threads, which create a secure seal when used with appropriate thread sealant or tape. The knurled control knob provides a tactile grip, allowing for easy adjustment without the need for additional tools. For MRO specialists and facility managers, the Western Enterprises 851-B represents a reliable solution for maintaining precise control over process variables.
