Specification

The LJ00684 is a power proportional solenoid valve (also referred to as a pump power proportional solenoid valve or hydraulic pump proportional solenoid) used in Sumitomo and CASE hydraulic excavators. It is an electro-hydraulic actuator that regulates the hydraulic pump power output by controlling the pump regulator's swash plate angle. The valve converts electrical current from the ECM into mechanical force, thereby adjusting the pump displacement to match engine power and workload demand.

LJ00684 Power solenoid valve is use for Sumitomo SH200-5 SH210-5 SH240-5 SH350-5 Case CX130 CX135SR CX160 CX210 CX240 CX290 CX330 CX350 CX700 CX800 Link-belt 130X2 130X3 210X2 240X3 350X3 370X2 450X2 470X2 490X3

1. Fit Sumitomo excavator: SH200-5, SH210-5, SH240-5, SH350-5;
2. Fit CASE excavator: CX130, CX135SR, CX160, CX210, CX240, CX290, CX330, CX350, CX700, CX800;

4. Fit excavator Link-belt: 130X2 130X3 210X2 240X3 350X3 370X2 450X2 470X2 490X3

Instruction for Use

The LJ00684 solenoid valve is mounted directly on the main hydraulic pump (pump regulator assembly), located beneath the rotating platform of the excavator. It is part of the pump control solenoid valve assembly that regulates the swash plate angle of the variable displacement pump. On Sumitomo SH200-5, SH210-5, SH240-5, and SH350-5 models, the LJ00684 is listed as the power proportional solenoid valve for the K3V160DTP pump. The same part number is listed for CASE CX-series excavators in the hydraulic pump control system section. The valve is typically mounted alongside the pump flow proportional valve (part number KHJ15460 assembly, fault code 7241), forming a pair of proportional solenoids that together manage pump output and power limiting.

The pump control system uses two distinct proportional solenoids on the pump regulator:

· LJ00684 — Power proportional solenoid (fault code 7240): Limits pump output based on engine load, preventing overload and stall.

· Flow proportional solenoid (fault code 7241): Regulates pump flow based on operator command and work mode.
