VALVE (P/N a1390) - As Removed

The a1390 is a metal-bodied aircraft valve designed to control and isolate fluid flow in hydraulic, fuel, and pneumatic systems. Internal seals provide reliable operation across aviation service conditions. This valve functions as a shutoff or flow control component in hydraulic line circuits, preventing unwanted fluid movement during maintenance or system isolation.

Installation requires proper flow orientation alignment, torque specifications per aircraft documentation, and verification against your system's Illustrated Parts Catalog to ensure compatibility with existing fittings and circuit requirements.

What is the VALVE (P/N a1390)?

The a1390 is a metal-bodied aircraft valve designed to control and isolate fluid flow in hydraulic, fuel, and pneumatic systems. Internal seals provide reliable operation across aviation service conditions.

What hydraulic fluid type is the a1390 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 against your aircraft maintenance manual for fluid compatibility.

Does the a1390 come pressure-tested and certified?

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