Legris 7669 08 10 Miniature Flow Control Valve 8mm

Product Description

The LEGRIS 7669 08 10 is a miniature air flow control valve designed for precise regulation of airflow in pneumatic systems. It accepts an 8mm outside diameter tube and connects via a 1/8 BSPP male thread, making it well suited for compact pneumatic circuits where space and accuracy both matter. The valve body is constructed from nickel-plated brass with internal components of nitrile butadiene rubber (NBR), stainless steel, and technical polymer, providing corrosion resistance and durability under continuous cycling. Maximum working pressure is rated at 145 psi. Pneumatic technicians and automation specialists typically install this valve in industrial and light commercial control systems.

This flow control valve is used in pneumatic actuator circuits, cylinder speed control applications, and air line assemblies where directional flow adjustment is required. Its miniature form factor makes it a practical choice for panel-mounted pneumatic systems, machine builder assemblies, and tight-space installations. The BSPP thread type is standard in metric and European-specification pneumatic systems, so verify thread compatibility with the mating fitting or manifold before installation.

Key Features

• Miniature form factor for compact pneumatic circuit installations
• 8mm tube outside diameter push-to-connect interface
• 1/8 BSPP male thread for metric and European-specification pneumatic systems
• 145 psi maximum working pressure rating
• Nickel-plated brass body with NBR seals and stainless steel internals for corrosion resistance
• Technical polymer components reduce weight while maintaining structural integrity

Compatibility

Designed for use in pneumatic systems accepting 8mm OD tube connections and 1/8 BSPP male fittings. Verify thread form and tube diameter against existing system specifications before installation.

Installation Notes

Installation is typically performed by pneumatic system technicians or industrial maintenance personnel. Depressurize and lock out the pneumatic circuit completely before removing or installing any flow control valve. BSPP threads are parallel and rely on a bonded seal or O-ring face seal for leak-free connection — do not use PTFE tape in place of the appropriate sealing method. After installation, gradually restore system pressure and verify there are no leaks before returning the circuit to service.
