Norgren 03041122 Roller Lever Valve 1/8 Inch Npt

Product Description

The NORGREN 03041122 is a mechanically operated directional control valve designed for pneumatic systems in industrial and automated machinery applications. It uses a packed spool design with a roller lever actuator and spring return, making it well suited for cam-operated or limit-switch-style actuation without the need for electrical signals. The valve offers a Cv rating of 0.340 and handles working pressures up to 10 bar. It features a 1/8 inch NPT inlet connection and a 3-port, 2-position configuration. Licensed pneumatic technicians and industrial maintenance professionals are the typical installers for this component.

This valve is used in pneumatic control circuits where mechanical actuation is preferred over solenoid or manual operation. Common applications include end-of-travel detection on actuators, safety interlocks, and machine guarding systems. The spring-return function ensures the valve defaults to its original position when the roller lever is released. The compact size and NPT threading make it straightforward to integrate into existing manifold or inline pneumatic plumbing in light industrial and manufacturing environments.

Key Features

• Packed spool valve design for reliable sealing and consistent actuation
• Roller lever actuator with spring return for cam-driven or mechanical trip applications
• 1/8 inch NPT inlet connection for standard pneumatic plumbing integration
• 3-port, 2-position configuration for directional flow control
• Cv rating of 0.340 suitable for low-flow pneumatic circuits
• Maximum working pressure of 10 bar with an operating temperature range of 32 degrees F to 158 degrees F

Compatibility

Designed as an OEM-style replacement or direct-fit component for pneumatic control systems requiring a 3-port, 2-position mechanically operated valve with a 1/8 inch NPT connection.

Installation Notes

Installation should be performed by a qualified pneumatic or industrial maintenance technician. Depressurize the pneumatic circuit fully before removing or installing any valve. Verify NPT thread engagement and use appropriate thread sealant rated for compressed air service. Confirm the roller lever position and cam geometry align correctly before returning the system to service.
