The DG4V32CMU6B660 valve is produced by Vickers within the DG4 Directional Valves series and directs hydraulic flow in automated circuits. It employs a closed-center spool so all ports are blocked in neutral, and a spring-centered arrangement returns the spool when power is removed. The direct-current solenoid draws 30 W, is wrapped with Class H insulation, and is covered by Class F encapsulation to survive elevated temperatures. A 100 percent duty cycle allows continuous energization without overheating. Under 20 L/min at 175 bar the spool reaches full stroke in 60 ms and returns in 40 ms, giving predictable sequencing. Ports P, A, and B tolerate pressures up to 350 bar (5000 psi), enabling the valve to serve high-pressure machinery without external relief devices.
The solenoid accepts a U-type ISO 4400 / DIN 43650 plug; with this connector installed the housing achieves IP67, guarding against dust and water. Mounting follows the ISO 4401-AB-03-4-A pattern, also called CETOP 3, and retention screws fit M5-0.8 or 10-24 UNC-2B threads to suit metric or imperial tooling. Hydraulic fluid must be filtered to ISO 4406 cleanliness class 19/17/14 to prevent spool wear. The coil operates correctly down to 90 percent of its rated supply voltage, allowing for line drops in long cable runs. These interface, protection, and cleanliness limits define the conditions under which the DG4V32CMU6B660 maintains reliable operation in industrial hydraulic automation.
