The KBFDG4V533C533C50ZM1PE7H11 valve is produced by Vickers for the Directional Control Valves series and shifts spool positions to route hydraulic flow in automated machinery. A 24 V DC coil energizes the pilot stage, while a ±10 V command signal sets the proportional position. There is a feedback sensor that confirms spool movement for closed-loop control. The single-stage design delivers quick response, and the P-blocked, A & B-to-tank spool configuration provides fail-safe pressure relief. The valve tolerates 315 bar on the P, A, and B ports, moves up to 50 L/min of oil, and limits pressure drop to 5 bar at that flow.
ISO 4401-05 (NFPA D05/CETOP 5) interfaces let the unit mount on standard manifolds, and the subplate mounting style keeps pipework undisturbed during replacement. The tank port withstands 210 bar, protecting the return circuit from overload. Fluorocarbon seals resist common hydraulic fluids, and the working temperature range of −20 °C to 85 °C supports outdoor or high-heat locations. No manual override is fitted, so electrical power is required for commissioning and troubleshooting. A 7-pin PE7 plug handles all valve wiring and simplifies field connection.
