Technical Specifications Parameter Specification / Description Notes Manufacturer / Series Eaton KCG Model Number KCG-6-W250-1-Z-M-U-HL1-10 Valve Type Stackable Inlet Section, Load Sensing, Proportional Section Function W250-1: Inlet Section with Compensator, Relief Valves & Power Beyond The core control unit for the pump. Porting Size 1-1/4" NPTF The "-6-" denotes the nominal port size. Maximum System Flow Up to 150 L/min (40 US gpm) Suitable for this port size. Maximum System Pressure 350 bar (5,000 psi) Actuation Type Proportional Solenoid (for any auxiliary functions on this section) The "-M-U-" denotes a wet-armature proportional solenoid. Electrical Connection -HL1- High-performance electrical connector for proportional valves. Control Signal Typically PWM (Pulse Width Modulation) or current The "-10-" often relates to the control electronics type. Main System Relief Setting Factory-set to a specific value e.g., 250 bar or 300 bar. Must be confirmed from technical drawing. LS Relief Valve Setting Typically 20-25 bar above the main system relief Protects the LS circuit. Setting is factory-defined. Compensator Margin Spring Typically set to a delta P of ~15-20 bar (200-300 psi) The pressure difference between pump output and the highest load signal.
