Nozzle flapper-type hydraulic servo amplifier with mechanical feedback function
The "KSVA Series" is a hydraulic servo amplifier that has been improved to allow users to adjust it according to the rated current value of the servo valve using an internal switch. It can accommodate servo valves with a rated current of up to 100mA. It has a built-in PID circuit and can accept up to two feedback signals. It is mainly used in devices for preventing lateral rolling of ships and can flexibly respond to specifications designated by customers as a rare domestic manufacturer.
