The KDG4V52C65SZMUH630 proportional valve belongs to the KDG Non-feedback Proportional Valves series and is manufactured by Vickers. It regulates hydraulic flow and pressure in automated machinery without internal feedback. The valve is solenoid controlled, so an electrical signal determines spool movement for proportional output. A 24 V DC coil voltage matches common industrial control power supplies. The spring-centered build returns the spool to neutral when power is removed, preventing unintended motion. Single-stage construction minimizes internal pressure loss and simplifies service. The ISO 4401-05 (NFPA D05, CETOP 5) interface lets the unit bolt directly to standardized subplates, while an ISO 4400 (DIN 43650) electrical connection provides a quick plug-in wiring method. Meter-out metering gives downstream flow control for smooth actuator deceleration, and the absence of a manual override eliminates unauthorized hand shifting.
A rated A-port flow of 65 L/min supports medium-capacity actuators, and the B-port carries the same 65 L/min to balance circuit performance. The valve withstands a maximum operating pressure of 315 bar, allowing use in high-pressure industrial presses and injection machines. Viton seals resist higher temperatures and aggressive hydraulic fluids, extending service life. An acceptable fluid cleanliness level of 17/15/12 prevents spool sticking and wear. Overall dimensions of 255.016 mm in length, 70.104 mm in width, and 106.172 mm in height help designers allocate manifold space accurately, and the compact footprint eases integration into crowded power units.
