China HITACHI EX120-1 TRACKING CONTROL VALVE PRESSURE SWITCH (TRACK SPEED SENSOR) (OEM HI 4259333) | Tonkee®

The primary function of the Tracking Control Valve Pressure Switch is to monitor the hydraulic pressure within the tracking control system.

The hydraulic system is responsible for controlling the movement of the excavator's tracks, allowing it to move forward, backward, and turn. The pressure switch continuously measures the hydraulic pressure, providing feedback to the excavator's control system.

Pressure Sensing:
The pressure switch is designed to detect variations in hydraulic pressure. It is calibrated to specific pressure levels relevant to the excavator's operation. When the pressure exceeds or falls below the set thresholds, the pressure switch sends signals to the excavator's control unit.

Control and Safety:
The information provided by the pressure switch is essential for maintaining precise control over the excavator's track speed. If the system detects an abnormal pressure level, it can trigger safety mechanisms to prevent potential issues such as over-speeding or loss of control. This contributes significantly to the safety of both the operator and the machine itself.

Compatibility and Reliability:
Being an OEM part, the HI 4259333 pressure switch is designed and manufactured to meet Hitachi's strict quality and compatibility standards.

This ensures a seamless fit within the EX120-1 excavator's hydraulic system and reliable performance under demanding conditions.

Durability and Longevity:
Construction machinery like excavators is subjected to harsh working environments, including dirt, debris, and extreme temperatures. The pressure switch is built to withstand these conditions, making it a durable and long-lasting component of the excavator.

Maintenance and Troubleshooting:
Routine maintenance of the pressure switch is essential to ensure it continues to function correctly. In the event of any issues with the tracking control system, the pressure switch can be a crucial component to inspect. If it malfunctions or fails, it can be replaced with an OEM part like the HI 4259333 to restore the excavator's tracking control functionality.
