High Response Directional and Flow Controls (EHDFG)
These valves pursue the ultimate performance of proportional electrohydraulic directional & flow control valves and make themselves to have high response features. The closed-loop is composed in the valve inside by combination of a differential transformer (LVDT) and a power amplifier. Thus, high accuracy and reliability are provided. In addition to control in the open-loop, these can be used for the closedloop system as simplified servo valves.
