Servo actuator [SOP series]

Electro-hydraulic servo actuator that realizes high-precision and high-speed response operation

High-end electro-hydraulic actuator equipped with a jet pipe (EOP type).
High precision and quick response enabled via a servo system incorporating electrical feedback and a servo amplifier instead of a mechanical restoration mechanism.
Electrical detection of feedback signals also allows configurations using separated cylinder.


Features

<High speed response realized. >
<Differing configurations with separate cylinders enable no restrictions with cylinder selection. >
High speed response achievable by setting the loop gain at a higher level for the entire servo system.
<Strong power ensures reliable operation. >
Each of the units making up the actuator is of a robust structure, so the actuator generates strong power.
Compared to servo valve-based units, the actuator with hydraulic jet pipe is basically free of operational failures due to dust or other foreign matters.
<A wide variety of types available>
Desired type selectable based on the operating force required at the operating end.
<Various additional other devices can also be added. >
Devices for manual operation, emergency operation, remote control and others can be added on.
Pressure switch, limit switch, opening degree transmitter and other devices also mountable.
