Overview
The Vickers KDG4V-3-2C15S-M-W-G-40 is a pilot-operated directional control valve from the KDG4V-3 series, part of Vickers’ established portfolio of proportional hydraulic control components. This 4-way valve provides precise directional control and modulation for industrial and mobile hydraulic systems, featuring proportional solenoid actuation for smooth spool movement and flow management.
Key Features
- 4-way directional control — routes flow to multiple load paths with proportional metering
- Pilot-operated solenoid — 24VDC activation with reduced power draw compared to direct-acting spools
- Proportional spool design — enables fine-tuned flow and pressure adjustments mid-cycle
- Closed-center configuration — default neutral position blocks flow; pilot signal enables directional change
- Rated to 5000 psi — suitable for high-pressure industrial and mobile equipment applications
