VALVE, CHECK (P/N 3-1582-2-1) - As Removed

The 3-1582-2-1 is a hydraulic check valve that permits one-way fluid flow while blocking reverse flow. This valve maintains system isolation and prevents backflow damage to pumps and actuators in aircraft hydraulic lines. Installed in hydraulic manifolds and circuit protection applications, the check valve ensures pressure integrity during normal operation and emergency conditions.

Installation requires correct flow orientation and proper sealing per aircraft maintenance manual specifications. Designed and tested to SAE ARP4946A guidance for aviation hydraulic systems.

What is the VALVE, CHECK (P/N 3-1582-2-1)?

The 3-1582-2-1 is a hydraulic check valve that permits one-way fluid flow while blocking reverse flow. This valve maintains system isolation and prevents backflow damage to pumps and actuators in aircraft hydraulic lines.

What hydraulic fluid type is the 3-1582-2-1 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, CHECK against your aircraft maintenance manual for fluid compatibility.
