Three series of Eaton’s Vickers directional proportional valves, series KBSDG-3/5, KBFDG-3/5 and KBHDG-5/7/8/10 11, with on-board electronics, are now available with the addition of 4-20mA control command options. Benefits of the new 4-20mA command option on these series include maintaining the integrity of the command signal over lengthy cable and improved noise immunity. These Vickers valves are used in heavy-duty applications including primary metals production, die-casting and foundry equipment, civil engineering, marine and offshore equipment, petrochemical, power generation and wood processing. KBFDG4V 3/5 valves are direct acting, solenoid-operated directional control valves with spool-position feedback controlled by an on-board amplifier. The valves are suitable for open and closed-loop systems. KBSDG4V 3/5 valves provide high dynamic response. They are direct acting, solenoid-operated directional control valves; spool-position feedback is controlled by the on board amplifier. The valves’ fast and accurate control makes them suitable for use in closed-loop applications requiring demanding and accurate control of actuator position, speed or pressure/load. The KBHDG5V 5/7/8/10 is two-stage, high flow, high dynamic response, pilot-operated, direct acting solenoid-operated directional-control valves. They are controlled by the on-board amplifier and have spool-position feedback on the pilot and main stage resulting in fast and accurate valve control. They are suitable for use in closed-loop applications requiring demanding and accurate control of actuator position, speed, pressure/load or any combination of these.
