An actuator that receives instrumentation signals of 4 to 20mA and then identifies the necessary mechanical movement such as rotation and direct advance of the operating axis that is proportional to that of the signal. Hydraulic oil generated in the hydraulic pump is injected from a jet pipe (hydraulic jet pipe relay mechanism). The force coil receiving the instrumentation signal swings the jet pipe in feeding the hydraulic oil into the cylinder and then the cylinder moves back and forth. It also rotates and makes the operating axis connected to it straight.
The movement of the operating axis is fed back to the jet pipe with a mechanical restoration mechanism.
We also have the SOP series available that is of high density and has good response through the creation of servo systems with electrical feedback instead of a mechanical restoration mechanism.
