Eaton has announced the addition of 4-20mA control command options to three series of Vickers directional proportional valves with on-board electronics.

This control command option is in addition to the voltage command already available on these valves.

Benefits of the new 4-20mA command option on KBSDG-3/5, KBFDG-3/5 and KBHDG-5/7/8/10 11 design series directional proportional valves include maintaining the integrity of the command signal over lengthy cable and improved noise immunity.

Colin Cooper, product manager of industrial controls at EMEA, said: ‘The -11 design series supersedes the existing -10 design series.

‘The new valves are completely backward compatible, electrically, hydraulically and mechanically.

‘They will be shipped from the factory with optimised adjustments that provide consistent flow gain and excellent reproducibility valve-to-valve.’ 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 ideal for use in closed-loop applications requiring demanding and accurate control of actuator position, speed or pressure/load.

The KBHDG5V 5/7/8/10 are 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 ideal for use in closed-loop applications requiring demanding and accurate control of actuator position, speed, pressure/load or any combination of these.
