That Eliminate Signal Loss, Improve Noise Immunity
EDEN PRAIRIE, Minn. … Diversified industrial manufacturer Eaton Corporation today announced that three series of Vickers® directional proportional valves with on-board electronics have been upgraded with a new 4-20 mA control command option. This control command option replaces the voltage command used on these valves.
Benefits of the new 4-20 mA 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.
“The new -11 design series supersedes the existing -10 design series,” said Wayne Wang, Eaton product manager, industrial valves. “The new valves are completely backward compatible, electrically, hydraulically and mechanically. They will be shipped from the factory with optimized adjustments that will provide both consistent flow gain and excellent reproducibility valve-to-valve, to provide a true “plug-and-play” solution.”
“All the customer has to do to take advantage of the 4-20 mA control technology is to select the model code option,” said Wang.
These Vickers valves are typically 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.
About the valves’ features:
• KBFDG4V 3/5 valves are direct acting, solenoid operated directional control valves, with spool position feedback controlled by an on-board amplifier. They valves provide a cost effective solution for both 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. Their fast, accurate control makes them ideal for use in closed loop applications requiring demanding and accurate control of actuator position, speed, pressure/load or any combination of them.
• 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 extremely fast, 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 them.
