Earthmoving Equipment Mechanic Interview Questions and Answers

A pressure relief valve is used to control and limit the pressure in a hydraulic system.

• The pressure relief valve is designed to open and release excess pressure when it reaches a predetermined level.

• It helps protect the system from damage due to overpressure.

• The valve allows the fluid to bypass the system and return to the reservoir, preventing damage to the components.

• It is typically located near the pump or in the main hydraulic circuit.

• To identify bypassing cylinders, you...read more
