Product Description

The 4622 is a hydraulic priority valve for nose landing gear systems. This valve ensures pump flow reaches critical NLG actuators during low-pressure conditions by closing or metering supply to nonessential users. Installed ahead of secondary system users in the NLG supply line, it preserves gear extension and steering capability when system pressure drops.

Installation follows aircraft maintenance manual specifications for proper positioning and pressure settings.
