A hydraulic actuator that receives an instrumentation signal of 4 to 20mA and then rotates the operating axis into the corresponding position. E/E positioner, hydraulic channel switching valve, hydraulic pump, and cylinder, etc. are all packaged in a compact form. It receives external instrumentation signals with a positioner in recognizing any deviation from the current position. The actuator switches the hydraulic channel in the direction that then counteracts that deviation and then rotates the operating axis into a position corresponding to the signal. Revolution speed of the operating axis features unique fractional deviation speed operation, thus realizing stable positioning without overshooting.
