Product Description
The p9-l3a is a pressure relief valve for aircraft hydraulic and pneumatic systems. This valve opens at a preset cracking pressure to protect pumps, lines, and actuators from overpressure conditions, then reseats at a lower pressure per SAE ARP4763/ARP4835A standards. Commonly installed on hydraulic manifolds in general aviation and corporate aircraft.
Installation and adjustment must follow the aircraft maintenance manual and approved data with IPC verification. Proper setting ensures system protection during pressure transients while maintaining operational reliability.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
