The DG4V3S22ALMUH560 directional valve is produced by Vickers and belongs to the DG4 Directional Valves series. It directs hydraulic flow in automation circuits where precise actuation is required. The valve accommodates a maximum operating pressure of 350 bar and supports a flow rate up to 40 l/min for medium-capacity cylinders and motors. A wet armature solenoid design keeps internal components lubricated and damped. Electrical switching delivers a response time on of 60 ms and a response time off of 40 ms, allowing predictable cycle timing. Installation uses the ISO 4401-AB-03-4-A mounting interface that matches the CETOP 3 / NFPA D03 pattern for compatibility with standard sub-plates.
The single solenoid assembly weighs 1.6 kg, simplifying manual handling during servicing. Continuous energization is possible because the unit is rated for a 100 % ED duty cycle while the coil consumes 30 W. Coil windings are insulated to Class H and the external encapsulation is built to Class F to manage thermal stress. Electrical connection is made through an ISO 4400 (DIN 43650) plug that also achieves IP67 ingress protection when properly sealed. System oil cleanliness must be maintained at ISO 4406 code 19/17/14 to protect the spool and bore. The design tolerates up to 210 bar on the tank line, preventing backpressure from disturbing spool centering.
