Norgren 12VB00418 Needle Air Flow Control Valve

Product Description

The NORGREN 12VB00418 is a needle-style air flow control valve designed to regulate airflow in pneumatic systems. Built with a brass body, it provides precise throttling control through an adjustable needle mechanism. The valve features a tube-to-NPT connection configuration with a 1/4 inch tube outside diameter and a 1/8 inch NPT inlet. It is well-suited for use in compressed air lines, pneumatic circuits, and instrumentation systems where controlled flow adjustment is required. Licensed HVAC technicians, mechanical contractors, and industrial maintenance professionals are the typical installers for this class of valve.

This valve is commonly installed in light industrial and commercial pneumatic control applications. It is used in air-actuated systems, panel-mount assemblies, and compressed air distribution lines where fine flow adjustment is needed. The tube-to-NPT design allows direct connection to standard NPT-threaded ports while accommodating tubing on the opposing side, making it adaptable to a range of pneumatic plumbing configurations. At 0.11 pounds, it is compact and lightweight for easy inline installation.

Key Features

• Needle valve design allows precise manual adjustment of airflow rate
• Brass body construction offers durability and resistance to corrosion in pneumatic service
• Tube x NPT connection accommodates 1/4 inch OD tubing with a 1/8 inch NPT port
• Compact and lightweight at 0.11 pounds for use in space-constrained installations
• Sold individually as a single-piece unit

Compatibility

Designed as an OEM-style replacement or new-installation component for pneumatic flow control applications using 1/4 inch OD tubing and 1/8 inch NPT-threaded ports in compressed air systems.

Installation Notes

Installation is typically performed by licensed pipefitters, pneumatic system technicians, or industrial mechanical contractors. Depressurize and isolate the pneumatic circuit completely before removing or installing any flow control valve. Use appropriate thread sealant on NPT connections per applicable plumbing and mechanical codes. Avoid overtightening the needle adjustment to prevent damage to the internal seat.
