Case Excavator Solenoid Valve KHJ15440

The KHJ15440 operates as a pilot pressure control manifold. Each of the three solenoid valve sections receives a PWM (Pulse Width Modulation) signal from the ECM. The duty cycle of the PWM signal determines the current flowing through each coil, which in turn controls the position of the valve spool and the hydraulic pilot pressure delivered to the corresponding main control valve spool. This enables the ECM to independently control multiple hydraulic functions with precise proportional response.

Installation Position on Machine

The KHJ15440 solenoid valve group is mounted in the pilot hydraulic circuit of the excavator, typically located on or near the main hydraulic pump assembly or the main control valve on the upper structure of the machine. It is a bolt-on assembly that serves as the central

interface between the ECM's electrical control signals and the hydraulic pilot pressure system. On Sumitomo SH80BS-6A and SH80-6 models, the KHJ15440 is listed in the electrical parts section of the parts catalog as the standard 3-bank solenoid valve (24V), alongside the 2-bank valve KHJ14000. The same part number is listed for CASE CX80C and CX135SR excavators in the hydraulic control system section
