KBFDG4v533c50nzpe7h710

The KBFDG4v533c50nzpe7h710 valve belongs to the Directional Control Valves series and is produced by Vickers for hydraulic automation circuits that need electrically commanded flow direction. A solenoid-controlled actuation system shifts the spool when a 24 VDC coil is energized, allowing remote operation from standard machine control voltage. The electrical interface is a 7-pin connector with plug PE7, which provides a sealed and serviceable link between the valve and its power or feedback leads. A built-in feedback sensor reports spool position to the controller so closed-loop accuracy can be maintained. There is no manual override, preventing unauthorized or accidental spool movement in safety-critical equipment. The spool arrangement is P blocked with A, B, and T connected, a pattern selected for circuits that need pump isolation while permitting actuator bypass. Single-stage construction simplifies the hydraulic path and minimizes response time. Subplate mounting lets technicians replace the unit without disturbing hard plumbing, and the ISO 4401-05 (NFPA D05, CETOP 5) interface keeps it interchangeable with other size-05 hardware.

The valve accepts working pressures up to 315 bar, so it can be installed on presses or machine tools that operate at high system pressure. The tank port is rated for 210 bar, enabling reliable return flow even when back pressure is present. Rated flow is 50 L/min through the A port and the same 50 L/min through the B port, and this symmetric flow rating ensures equal actuator speed in both directions. Meter-in/meter-out metering gives designers a way to control acceleration and deceleration by throttling either the supply or return line. A measured pressure drop of 5 bar at the rated flow indicates the energy loss users must account for when sizing the power unit. Because symmetric flow is confirmed, matching performance can be expected regardless of which service port is pressurized. These hydraulic characteristics combine with the subplate footprint to make the single-stage valve a compact choice for motion control where repeatability, feedback monitoring, and standardized mounting are required.
