1 MPa Vickers Solenoid Servo Valve KFDG4V5-33C70N-Z-VM-U1-H7-20-E-N56 Servo Control

The KFDG4V5-33C70N-Z-VM-U1-H7-20-E-N56 valve features a spore + body structure, designed primarily for closed-loop control systems in hydraulic applications. This servo control valve offers precise flow and direction control with its advanced proportional electromagnet driving mechanism.

Key technical features include:

• Spore + body construction for enhanced durability
• Proportional electromagnet driving mechanism
• Valve body doubles as a sleeve for compact design
• Manual reversing spring or steel ball positioning for automatic reset
• Check valve prevents oil backflow
• Relief valve controls system pressure
• Optional overload valves for different actuator load requirements

The valve operates as a direct-acting electro-hydraulic proportional direction throttle valve, with oil port connections (P, A, B, T) that shift proportionally to input current. The center spring mechanism ensures precise control with response frequencies up to tens of Hz.
