The KBFDG4V-5-2C50N25-Z-M1-PC7-H7-11 valve is manufactured by Vickers for the Directional Control Valves series and directs hydraulic flow to cylinders or motors based on electrical command signals. A single stage design enables direct spool actuation without a pilot section, keeping response straightforward. The spool uses a closed center arrangement so all ports are blocked in the neutral position to hold actuators steady. Subplate mounting simplifies replacement, and the interface matches ISO 4401-05, NFPA D05, CETOP 5, and NG10 patterns for compatibility with common manifolds. Electrical input is a 24 VDC solenoid that can draw up to 3 A, information that defines the power module needed for drive. A 7-pin PC7 connector is supplied without a plug so installers can choose their own cable assembly. The integrated ±10 V feedback and monitor signal lets motion controllers verify spool position for closed-loop accuracy.
For flow performance, the valve passes 50 L/min at rated command while producing a 5 bar pressure drop, balancing control authority with energy use. It tolerates system pressures up to 315 bar at its work ports and 210 bar on the tank port, allowing operation in high-pressure circuits such as industrial presses. Acceptable fluid temperature reaches 85 °C, keeping the unit stable in warm reservoirs. A cleanliness level of 17/15/12 is required to protect the precision spool lands from wear. The valve handles antiwear mineral oils and non-alkyl phosphate ester fluids, giving flexibility when fire-resistant media are specified. An assembled weight of 16.76 lb influences manifold support and maintenance handling. Together, these characteristics define a proportional control element suited for automation tasks that demand consistent directional flow control under demanding hydraulic conditions.
