The KBDG4V-3-33C13N-Z-M1-PE7-H7-10 directional valve belongs to the Directional Control Valves series and is produced by Vickers to switch and modulate hydraulic flow in automated machinery. It operates with an amplifier supply voltage of 24 VDC, matching the power rails commonly found in control panels. A ±10 VDC command signal input lets motion controllers generate proportional spool displacement for flow regulation. The valve uses a 7-pin plug with a mating half for its electrical connection, simplifying field wiring and removal. An IP65/IP67 enclosure rating protects the solenoids and electronics against dust and water jets encountered on industrial equipment. The assembly is subplate mounted and fits the ISO 4401-03-02-0-94 (D03) interface, so it can replace or upgrade standard D03 valve stations. Meter-in and meter-out metering ensures symmetrical flow control in both directions of movement. A spring-centered dual-solenoid spool arrangement returns the element to center when commands are absent, contributing to predictable circuit standby behavior.
The valve maintains full performance within an ambient temperature range of 0 °C to 70 °C, matching the oil temperature range of 0 °C to 70 °C so the hydraulic fluid and surrounding environment share the same limits. A pressure rating of 350 bar (5000 psi) on ports P, A, and B allows installation in high-pressure systems without derating. The rated flow of 13 L/min at a 5 bar pressure drop per path defines the expected volume capacity during normal operation. At center position the spool blocks port P while ports A and B bleed to tank, minimizing standby energy loss. Hysteresis is kept below 1 % of maximum stroke to support repeatable positioning of actuators. A 17 ms step response from 0 % to 100 % command provides rapid flow changes for dynamic cycles. The design includes no manual overrides, which prevents unauthorized mechanical actuation in safety-critical circuits.
