The KBCG-3-L250D-Z-M1-3-A-PE7-H1-10-P15-T10 proportional valve is manufactured by Vickers within the Proportional Valves series and regulates flow and pressure in hydraulic automation. Its solenoid-controlled actuation relies on a 24 VDC coil that draws 1.6 A, translating a ±10 V command input into precise spool movement. A 7-pin connector with plug type PE7 forms the electrical interface, while subplate mounting on the ISO 4401-03 / NFPA D03 / CETOP 3 pattern allows straightforward installation on standard manifolds. The single-stage construction shortens internal flow paths, and an 80 ms long ramp time moderates command changes to limit hydraulic shock. No manual override is included, preventing unintended actuation during service.
The valve meters up to 5.0 L / min (1.3 US gpm) and regulates outlet pressure from 5 to 250 bar, withstanding peaks to 350 bar without structural compromise. Compatibility with antiwear hydraulic oils maintains seal integrity and lubrication under continuous duty. Operation is specified between −20 °C and 70 °C, covering typical industrial and mobile temperature ranges. These flow, pressure, and temperature capabilities define a working envelope suited to fine control of small cylinders, precision actuators, and other low-flow hydraulic loads.
