VALVE CHEK (P/N 3171-00) - As Removed

The 3171-00 is a check valve that allows fluid flow in one direction while blocking reverse flow in aircraft hydraulic and pneumatic systems. This one-way valve protects downstream components from backflow pressure spikes and system contamination. Installed in pressure lines throughout fuel, hydraulic, and environmental control systems, the valve maintains system integrity during normal operation and emergency conditions.

Installation requires proper orientation per the aircraft maintenance manual and Illustrated Parts Catalog. Verify system pressure ratings and cleanliness requirements before installation.

What is the VALVE CHEK (P/N 3171-00)?

The 3171-00 is a check valve that allows fluid flow in one direction while blocking reverse flow in aircraft hydraulic and pneumatic systems. This one-way valve protects downstream components from backflow pressure spikes and system contamination.

What hydraulic fluid type is the 3171-00 compatible with?

Hydraulic component compatibility depends on the aircraft system design. Common aviation hydraulic fluids include MIL-PRF-5606 (mineral-based), MIL-PRF-83282 (synthetic), and Skydrol (phosphate ester). Verify the VALVE CHEK against your aircraft maintenance manual for fluid compatibility.

Does the 3171-00 come pressure-tested and certified?

Overhauled and repaired hydraulic components are pressure-tested per manufacturer specifications and include 8130-3 documentation. The VALVE CHEK is available in: As Removed. Contact us for test documentation on your selected condition.
