F15-DG4S4-012C-U-D-60

The F15-DG4S4-012C-U-D-60 belongs to the DG4 Directional Valves series from Vickers and is intended for automated hydraulic circuits where electrical actuation must shift flow paths reliably. Solenoid operation allows remote switching without manual intervention, supporting quick cycle changes in machine sequences. A Class F encapsulated coil shields the windings from vibration and moisture, while Class H insulation withstands elevated temperatures generated during service. The coil is rated for 220 VAC at 50 Hz or 240 VAC at 60 Hz, allowing straightforward connection to common industrial mains. Continuous operation is possible because the duty cycle is 100 % ED, eliminating the need for cooling pauses. Reliable pull-in is maintained when supply voltage is at least 90 % of nominal, ensuring stable performance during brief drops in plant power.

Ingress protection is IP67 when an ISO 4400 plug is fitted, so the valve resists dust and temporary immersion in wash-down environments. A maximum flow capacity of 95 L/min permits it to handle medium-to-high throughput circuits without excessive pressure loss. The P, A, and B ports tolerate pressures up to 350 bar (5000 psi), enabling use in high-pressure actuator lines, while the T port is limited to 210 bar (3000 psi) to suit return paths. Operation with petroleum-based oils guarantees compatibility with common hydraulic fluids, provided cleanliness is maintained at 20/18/15 per ISO 4406 to protect internal metering edges. There is no indicator light, which reduces envelope size and simplifies wiring for installations where visual coil status is monitored elsewhere.
