The KBCG-3-L250D-Z-M1-3-A-PE7-H1-10-P15-T12 proportional pressure relief valve belongs to the Pressure Control Valves series manufactured by Vickers. It is installed to limit hydraulic pressure in automation systems. Solenoid control enables remote adjustment of the relief setting, and the single stage design keeps the flow path short for quick response. A left-hand build orientation positions the pilot and electrical parts on the left side to suit matching manifold layouts. The valve mounts on a subplate and follows the ISO 4401-03 (CETOP 3/NFPA D03) interface, so it aligns with common industrial manifolds without adapters. It passes up to 5 L/min and withstands system pressures as high as 350 bar before opening. Buna-N sealing contains mineral-oil media and resists wear produced by standard hydraulic fluids. These characteristics allow reliable over-pressure protection within compact hydraulic modules.
On-board electronics process a ±10 V command input and translate it into proportional coil force, eliminating the need for external amplifiers. The coil operates at 24 V DC and draws 1.6 A, creating the magnetic field required to modulate relief pressure. A 7-pin connector with plug forms the electrical interface and allows quick disconnection during maintenance. The valve requires fluid cleanliness of ISO 4406 17/15/12 to prevent silt from affecting the pressure control element. Total product weight is 4.85 lb, so the unit can be supported by light aluminum subplates in mobile or stationary equipment. These electrical and contamination control parameters ensure consistent pressure regulation when the valve is integrated into automated hydraulic machinery.
