The CG5100ACVMUB6110 valve is produced by Vickers within the Pressure Control Valves series and is intended to maintain stable hydraulic pressure in automated circuits. It is a pilot operated relief valve that diverts excess flow back to tank to protect downstream components. The unit works in a two stage configuration so the pilot section tunes the main stage for responsive pressure control. Actuation is solenoid operated, enabling electronic on-off or proportional shifts from a remote controller. The coil accepts a 120 VAC, 60 Hz supply, allowing direct connection to standard industrial power. Electrical termination is made through an ISO 4400 (DIN 43650) connector, which simplifies field replacement and ensures consistent sealing around the contacts. The valve mounts on a subplate or manifold, letting designers place it close to the actuator without custom piping.
The assembly tolerates a maximum system pressure of 210 bar (3000 psi) while limiting return line pressure to 155 bar (2250 psi) to match typical reservoir ratings. It passes flow up to 454 L/min (120 US gpm), supporting high-capacity pumps in mobile or stationary equipment. Petroleum-based hydraulic oils are specified as the compatible fluid, and operation requires an ISO 19/17/14 cleanliness level to protect internal metering edges. Nitrile seals contain the fluid and withstand common additives used in standard oil formulations. Service temperatures can reach 70 °C without loss of function, covering the range found in most power units. Physical dimensions of 256.286 mm in height, 146.050 mm in length, and 85.852 mm in width help engineers verify clearance when stacking multiple valves on a common manifold.
