Legris 7645 04 11 Miniature Swivel Flow Control Valve

Product Description

The LEGRIS 7645 04 11 is a miniature swivel outlet flow control valve designed to regulate airflow in pneumatic systems. It uses a tube-to-NPT connection, accepting a 5/32 inch tube OD on one end and a 1/8 inch male NPT thread on the other. The nylon body keeps weight low at 0.02 pounds, making it well suited for compact pneumatic circuits where space and weight are critical. The swivel outlet design allows the tube fitting to rotate during installation, reducing hose stress and simplifying routing. This valve is installed by pneumatic system technicians and industrial maintenance professionals working on compressed air or vacuum circuits.

This valve is suited for use in miniature pneumatic control circuits found in light industrial, automation, and instrumentation applications. The outflow control configuration meters air exiting an actuator or component, providing speed control on the exhaust side of the circuit. Its full vacuum rating extends its usefulness to vacuum-handling applications as well as standard compressed air systems. The 1/8 inch NPT male thread fits standard ported manifolds, cylinders, and inline fittings common in small-bore pneumatic assemblies.

Key Features

• Swivel outlet design allows tube angle adjustment during and after installation to reduce hose strain
• 5/32 inch tube OD push-to-connect style inlet for quick, tool-free tube insertion
• 1/8 inch male NPT thread for direct porting into standard pneumatic components
• Nylon body construction offers lightweight, corrosion-resistant performance
• Full vacuum rating supports both compressed air and vacuum circuit applications
• Outflow control meters exhaust-side airflow for actuator speed regulation

Compatibility

Designed as an OEM-style replacement or new-installation flow control for miniature pneumatic circuits using 5/32 inch OD tubing and 1/8 inch NPT ported components.

Installation Notes

Installation is performed by qualified pneumatic or industrial maintenance technicians. Depressurize and lock out the pneumatic system before removing or installing any flow control fitting. Hand-tighten the NPT thread first, then apply wrench torque only as needed to achieve a leak-free seal without cracking the nylon body. Verify tube is fully seated in the push-to-connect fitting and confirm no leaks under pressure before returning the system to service.
