The KBHDG4V38XM1PE712 valve is produced by Vickers for the Directional Control Valves series and is used to regulate flow direction in hydraulic automation loops. It functions as a proportional pilot valve, so spool shift is proportional to a command signal for precise motion control. The single-stage design shortens the hydraulic path and improves response time. An ISO 4401-03 (NFPA D03, CETOP 3/NG06) interface lets the unit bolt directly to standard NG06 manifolds, while subplate mounting permits quick swap-out without disturbing pipe runs. A 24 V DC coil energizes the pilot section, providing low-power actuation suitable for mobile or industrial supplies. The built-in driver accepts a ±10 V command input, allowing servo controllers to issue symmetric control signals. A 7-pin PE7 connector groups power, command, and monitor lines in one plug to simplify cabling, and on-board electronics remove the need for a separate amplifier card.
An internal feedback sensor reports spool position to the electronics, enabling closed-loop correction that holds flow accuracy under varying loads. System oil must remain at ISO 4406 cleanliness code 17/15/12 to protect the precision land edges from abrasion. Viton seals resist synthetic fluids and elevated temperatures, extending service life in demanding circuits. The housing measures 237.236 mm in length, 45.974 mm in width, and 115.824 mm in height, so it fits compact manifold stacks. Operating limits span from −20 °C to 70 °C, allowing reliable startup in cold facilities and safe running in warm environments.
