The KAHDG5V-7-2C200N-X-VM-PD7-H1-21 valve belongs to the DG5 Two-Stage Directional Valves series and is produced by Vickers for hydraulic automation where controlled flow direction is required. It mounts on an ISO 4401 size 07 (ANSI/B93.7M D07) interface so it integrates with standard subplates. The spring-centered spool returns to its neutral position automatically, while spool type 2 closes all ports to tank to halt actuator motion in center. A maximum flow of 300 L/min (80 US gpm) through spool 2 supports high-capacity circuits, and the main ports tolerate 350 bar (5000 psi) to suit heavy-duty machinery. The internal pilot supply feeds the control stage from system pressure, an external pilot drain routes spent fluid to tank to minimize back pressure, and the pilot circuit remains stable up to 350 bar (5000 psi) during peak demand.
Electrical and environmental characteristics support continuous service. A 24 VDC solenoid coil draws 30 W, Class H insulation resists elevated winding temperatures, and a 100 percent duty cycle allows uninterrupted energization. The IP65 enclosure prevents dust ingress and withstands water jets, while reliable operation is maintained from −20 °C (−4 °F) to 70 °C (158 °F). Pressure in the Y drain port is limited to 210 bar (3045 psi) to protect the pilot stage against back-pressure spikes. These specifications combine to give the KAHDG5V-7-2C200N-X-VM-PD7-H1-21 dependable directional control performance in demanding hydraulic circuits.
