Coilhose Pneumatics SV802 Inline Check Valve 1/4 in

Product Description

The COILHOSE PNEUMATICS SV802 is an inline safety excess flow check valve designed for compressed air and pneumatic fluid systems. Featuring female NPT connections on both ends, this valve allows flow in one direction while blocking reverse flow, protecting downstream components and preventing backpressure damage. The aluminum body keeps weight low while providing adequate durability for standard pneumatic service pressures. The 1/4 inch pipe size fits common branch and tool-line connections found throughout industrial and workshop pneumatic systems. Licensed pneumatic system technicians and pipefitters typically install this valve during new system assembly or as a replacement in existing lines.

This valve is suited for inline installation on 1/4 inch pneumatic lines in light industrial, workshop, and production environments. The FNPT x FNPT end configuration allows direct threading into standard pipe fittings, manifold ports, or air tool supply lines. Its excess flow check function makes it appropriate for safety-critical branch points where downstream line breaks or equipment failures could otherwise allow uncontrolled air discharge. The compact 1-3/8 inch body width allows installation in tight panel or cabinet runs where space is limited.

Key Features

• Inline valve configuration with FNPT x FNPT end connections for direct pipe installation
• Safety excess flow check valve function blocks reverse flow and limits downstream hazards
• Aluminum body construction for lightweight service in pneumatic applications
• 1/4 inch pipe size fits standard pneumatic branch and tool-supply lines
• Compact 1-3/8 inch body width suits installations with limited clearance

Compatibility

Designed as an OEM-style inline check valve replacement for 1/4 inch FNPT pneumatic piping systems requiring safety excess flow protection.

Installation Notes

Installation should be performed by a qualified pipefitter or pneumatic systems technician. Depressurize and lock out the air supply before removing any existing valve or fitting. Apply thread sealant tape or compound to NPT threads per the applicable piping code before threading the valve into place. Verify flow direction arrow or valve orientation before pressurizing the system.
