The depressurization valve on the backup pump reduces output pressure during startup of which component?

Explanation:
During startup of the electric-motor driven backup hydraulic pump, a depressurization valve limits its output. This soft-start approach prevents a sudden pressure spike in the hydraulic system as the pump comes up to speed, protecting lines and actuators and allowing a controlled build-up of pressure until normal operation is reached.
