The KDG4V32C03FHMUHA760 valve belongs to the KDG Non-feedback Proportional Valves series and is manufactured by Vickers for hydraulic automation where proportional flow control is required. It installs on an ISO 4401-03 (NFPA D03/CETOP 3) interface so it can be mounted on standard subplates. The spool is configured for a closed center condition, allowing all ports to be blocked in neutral to hold load position. Fine meter-in and fine meter-out metering give precise flow adjustment in both directions of movement. A rated flow of 3 L/min per path supports small actuator circuits while limiting energy loss. The unit tolerates up to 350 bar operating pressure, with the tank line restricted to 210 bar to protect return plumbing. Its ISO 4401-AB-03-4-A mounting pattern matches many manifolds, and the overall length of 237.998 mm permits compact installation inside hydraulic cabinets.
The proportional solenoid uses a 24 V DC coil, making it compatible with common mobile and industrial power supplies. Coil resistance of 22.1 Ω at 20 °C defines the steady-state current, and a 55 mH inductance at 1 kHz influences the dynamic response to command signals. Maximum coil current is limited to 0.94 A at 50 °C to avoid overheating, assisted by a 100 % duty cycle rating that allows continuous energization. An ISO 4400 (DIN 43650) electrical connector provides quick disconnection for maintenance, and the IP65 ingress rating guards internal components against dust and water jets. A water-resistant manual override lets technicians shift the spool mechanically during power loss or commissioning. These electrical and environmental features ensure reliable proportional control when the valve is integrated into machines working under demanding operating cycles.
