Legris 7894 08 13 Flow Control Valve 8mm Push-to-connect

Product Description

The LEGRIS 7894 08 13 is a piloted non-return valve with integrated flow regulator and exhaust function, designed for pneumatic circuit control in compressed air systems. The body is constructed from nickel-plated brass for corrosion resistance in industrial service environments. Connecting via a push-to-connect fitting, it accepts an 8mm outside diameter tube and threads into a 1/4 BSPP male port. The Buna Nitrile o-ring seals provide dependable performance across typical pneumatic operating conditions. This valve is installed by instrumentation technicians, industrial maintenance mechanics, or pneumatic system specialists working on automation and fluid power equipment.

The 7894 08 13 is suited for use in pneumatic control panels, actuator circuits, and automation systems where controlled directional airflow and exhaust regulation are required. Its piloted non-return design allows flow in one direction under pilot signal while the integrated flow regulator controls exhaust rate. The push-to-connect interface simplifies tube installation and removal without additional fittings. Applications include factory automation, packaging machinery, and process control systems utilizing 8mm pneumatic tubing with BSPP-threaded ports.

Key Features

• Piloted non-return function with integrated flow regulator and exhaust control in a single body
• Nickel-plated brass body for corrosion resistance in industrial environments
• Push-to-connect fitting accepts 8mm OD pneumatic tubing for tool-free tube insertion
• 1/4 BSPP male thread for direct connection to standard metric-threaded pneumatic ports
• Buna Nitrile o-ring seals compatible with standard compressed air service
• Compact form factor at 2.5 inches height and 2.25 inches width and length

Compatibility

Designed for pneumatic systems using 8mm outside diameter tubing and 1/4 BSPP male-threaded ports. Suitable as a replacement or new-installation component in compressed air circuits requiring piloted non-return and exhaust flow regulation.

Installation Notes

Installation should be performed by a qualified instrumentation technician or pneumatic systems mechanic. Depressurize and lock out the pneumatic circuit fully before removing or installing any valve. Confirm thread form compatibility - BSPP is a parallel thread and typically requires a bonded seal or o-ring face seal rather than thread-sealing tape alone. Verify tube OD is exactly 8mm before insertion into the push-to-connect collet to ensure a leak-free connection.
