KDG4V Series Proportional Solenoid Control Valves

Product Overview: The KDG4V series consists of high-performance proportional solenoid-operated directional valves designed for hydraulic circuits requiring precise speed control, pressure regulation, or positioning synchronization. As a direct-operated proportional valve, it regulates flow and direction in direct proportion to the input electrical current. This series is widely utilized in injection molding machines, blow molding equipment, metal presses, and complex automated production lines. Its rugged sealing and precision-ground spool ensure minimal hysteresis and exceptional dynamic stability.

Featured models include: KDG4V-3S-33-C22A-M-U-H5-60 and KDG4V-3-2C20N-M-U-H7-60.

Key Technical Advantages:

• Precision Proportional Regulation: Driven by proportional solenoids, enabling stepless control over actuator speed and eliminating mechanical shocks common with standard on/off valves.

• Rapid Dynamic Response: Optimized internal flow passages and lightweight spool design ensure swift reaction to electronic controller commands, ideal for high-precision closed-loop control.

• Series 60 Design Standards: Represents the proven industrial standard with enhanced pressure ratings and minimized internal power losses.

• Flexible Electrical Configurations: Supports various connector options (e.g., M, U variants) with robust resistance to electromagnetic interference (EMI).
