Legris 7870 10 13 Soft Start Air Flow Control Valve

Product Description

The LEGRIS 7870 10 13 is a soft start air flow control valve designed for pneumatic systems that require controlled pressure buildup on startup. The soft start function gradually introduces supply pressure to downstream components, protecting actuators, cylinders, and tooling from sudden pressure surges. The valve accepts a 10mm tube outside diameter and is rated for a maximum working pressure of 145 psi. The body is constructed from nickel-plated brass with nitrile butadiene rubber (NBR) seals and technical polymer components. This valve is typically installed by pneumatic system technicians and industrial maintenance professionals in compressed air distribution circuits.

This valve is suited for use in industrial and commercial compressed air systems where controlled soft startup is required. Common applications include assembly automation, pneumatic conveying systems, and machine tool circuits where sudden pressure application could damage downstream equipment or cause unsafe motion. The 1/4 inch BSPP male thread connection makes this valve compatible with metric and BSP-threaded pneumatic plumbing common in European-standard equipment and imported machinery.

Key Features

• Soft start function gradually builds pressure to protect downstream pneumatic components
• Rated to 145 psi maximum working pressure
• Accepts 10mm outside diameter tubing
• Nickel-plated brass body for corrosion resistance in compressed air service
• NBR seals suitable for standard compressed air and many hydraulic media
• 1/4 inch BSPP male thread for metric and BSP pneumatic system integration

Compatibility

Designed for use in pneumatic systems utilizing 10mm OD tubing and 1/4 inch BSPP male threaded fittings, consistent with European-standard compressed air plumbing configurations.

Installation Notes

Installation should be performed by a qualified pneumatic technician familiar with compressed air system plumbing and applicable safety standards. Depressurize and lock out the compressed air supply completely before installing or removing any pneumatic valve. BSPP threads require appropriate thread sealant or tape rated for compressed air service. Verify that system pressure does not exceed the 145 psi maximum working pressure rating of this valve before returning the circuit to service.
