Hydraulic pump solenoid valve (regulator angle sensor) 9745876

Part number 9745876 hydraulic pump solenoid valve, also known as regulator angle sensor/displacement sensor, is compatible with Hitachi EX120-5, EX200-5, EX210-5, EX220-5 excavators and installed on the hydraulic main pump lifter. This component has dual functions of solenoid valve drive and angle signal acquisition, real-time monitoring of the angle of the main pump's inclined plate, feedback signal to the computer board, precise control of the main pump displacement and output flow, and matching mining load changes. The aging of the sensor coil and the sticking of the valve core can cause problems such as weak excavation, unstable movement speed, stalling and falling speed, and hydraulic system alarms. The product adopts precision valve core and high-precision sensing elements, which are resistant to vibration and high temperature in the engine room. The plug interface and installation size are consistent with the original factory, and can be directly replaced. Both original and high-quality aftermarket parts can be supplied, supporting accurate selection through part number verification.
