Legris 7640 04 20 Swivel Outlet Flow Control Valve 5/32

Product Description

The LEGRIS 7640 04 20 is a miniature swivel outlet flow control valve designed for precise airflow regulation in compressed air and pneumatic systems. The valve features a tube-to-NPT connection configuration with outflow control, meaning flow is restricted in the outlet direction while allowing free flow in the inlet direction. The nylon body keeps the assembly lightweight at 0.02 pounds, making it suitable for compact pneumatic circuits where space and weight are constraints. A 10-32 UNF male thread connects to the manifold or fitting side, while the push-to-connect end accepts 5/32 inch outside diameter tubing. Pneumatic technicians and automation service professionals are the primary installers of this component.

This valve is well suited for small-bore pneumatic circuits found in light industrial equipment, automated assembly fixtures, and instrumentation panels. The swivel outlet design allows the tubing exit angle to be adjusted after installation, reducing strain on tubing runs in tight enclosures. Full vacuum rating makes it usable in both pressure and vacuum applications. It is sold individually and packaged as a single unit.

Key Features

• Outflow control restricts airflow on the outlet stroke for precise actuator speed control
• Swivel outlet rotates after installation to accommodate tight routing without tubing stress
• Nylon body construction reduces weight and resists corrosion in clean compressed air environments
• 10-32 UNF male thread provides compatibility with standard miniature pneumatic manifolds and fittings
• Full vacuum rating supports use in both positive pressure and vacuum pneumatic circuits
• Accepts 5/32 inch outside diameter tubing for integration into small-bore pneumatic systems

Compatibility

Designed as an OEM-style replacement or addition for miniature pneumatic circuits using 5/32 inch outside diameter tubing with 10-32 UNF male NPT connections in compressed air or vacuum applications.

Installation Notes

Installation is typically performed by pneumatic technicians or automation service professionals. Depressurize the pneumatic circuit completely and verify zero pressure before removing or installing flow control valves. Hand-tighten the threaded male connection first, then snug with a wrench to avoid cracking the nylon body — do not overtighten. Confirm tubing is fully seated in the push-to-connect collet and that the swivel outlet is oriented to the intended routing direction before pressurizing the system.
