Product Description
The P25-349A450 is an adjustable relief valve for aircraft hydraulic and pneumatic systems. This spring-loaded component limits system pressure to protect downstream actuators and components from overpressure damage. The valve opens when pressure exceeds the set cracking pressure, venting excess fluid to maintain safe operating limits.
Installed in pressure control manifolds or main system lines, it requires calibrated equipment to set and verify cracking pressure during maintenance. Conforms to aerospace standards including SAE ARP4763 for pressure control reliability.
