The KFDG4V32C07NZMU1H720 valve is produced by Vickers and belongs to the Directional Control Valves series for precision hydraulic automation. It installs on an ISO 4401-03 (NFPA D03) pattern, allowing easy substitution in manifolds. Meter-in/meter-out metering supports separate control of acceleration and deceleration when driving cylinders or motors. A spool flow rating of 7 L/min at a 5 bar pressure drop suits positioning tasks that demand fine resolution rather than bulk flow. Port P, A, and B pressure capability reaches 350 bar, while the T port handles up to 105 bar, so the return line can be sized for moderate back pressure without compromising supply. The solenoid presents 1.87 Ω resistance at 20 °C and can draw 2.7 A at 50 °C, giving drive cards clear limits for current regulation. Connection is made through an ISO 4400 (DIN 43650) plug, and the absence of a manual override ensures that all actuation is commanded electrically.
A step response of 18 ms from 0 to 100 percent stroke enables quick directional changes, and hysteresis below one percent of maximum stroke keeps flow repeatable during small command reversals. The enclosure carries an IP65 rating, blocking dust and low-pressure water jets so the valve can be mounted near production lines that are cleaned with spray. Maximum ambient and oil temperatures are both specified at 60 °C, maintaining consistent performance in warm machinery enclosures. System fluid must meet ISO 4406 cleanliness level 17/15/12 to protect the precision spool lands, and the design is compatible with AW mineral oils or non-alkyl phosphate esters, letting the same hardware run in standard or fire-resistant circuits. Combined, these attributes allow stable proportional control in compact hydraulic axes exposed to demanding industrial conditions.
