Hydraulic Flow Control
The solenoid regulates hydraulic fluid flow to specific components such as the boom, arm, or bucket. This ensures precise control during digging, lifting, and other operations.
Fuel Injection Regulation
In the engine system, the solenoid helps manage fuel injection timing and quantity, contributing to better fuel efficiency and smoother engine performance.
Engine Start/Stop Control
Some solenoids are responsible for starting or shutting down the engine by controlling the electrical current to the starter motor or fuel shut-off valve.
Safety Lock Function
The solenoid often acts as part of a safety lock system, preventing unintended movement of the excavator’s arm or other hydraulic functions when the machine is not in operation or in a safe mode.
Attachment Switching
Solenoids can control the switching between different attachments (like a breaker, auger, or grapple) by directing hydraulic pressure to the correct auxiliary circuit.
