Vickers CG5V Proportional Valve | CG5V-8BM | CG5V-6FW | CG5V-6CW | Pilot Operated Electro-Hydraulic Control

Vickers CG5V Series Pilot-Operated Proportional Directional Valves

Product Overview: The Vickers CG5V series represents an advanced line of pilot-operated proportional valves designed for sophisticated industrial applications. By utilizing a proportional solenoid pilot stage to drive a large-bore main spool, this series enables stepless, precise regulation of acceleration, velocity, and direction for hydraulic actuators (e.g., heavy-duty presses, injection molding units). The CG5V combines high-performance proportional solenoids with a rugged valve body, maintaining exceptional linearity and ultra-low hysteresis even under high flow and high-pressure drop conditions.

Featured models include: CG5V-8BM-D-MU-HL5-20 EN7, CG5V-6FW-D-M-U-B-20, and CG5V-6CW-D-M-U-H7-11.

Key Technical Advantages:

• Two-Stage Proportional Logic: The proportional solenoid pilot stage enables precise control of hydraulic flows reaching several hundred liters per minute with minimal electrical input signals.

• Superior Dynamic Response: Optimized spool geometry ensures smooth acceleration and deceleration, effectively neutralizing hydraulic shocks during start-stop cycles.

• Versatile Configuration Options: * MU/H7/HL5: Specific electrical connection and manual override variants to suit diverse field requirements.

  • D (Internal Pilot): Features internal pilot pressure supply, simplifying system piping layouts.

• Industrial-Grade Reliability: Rated for pressures up to 31.5 MPa (315 bar), engineered for continuous 24/7 operation in demanding heavy-industrial environments.
