Locators can be adjusted from the host instrument DC 4-20mA signal and the lower actuator potentiometer ' wire ' signal (valve position feedback signal or DC4-20mA), the output of ' open ' and ' closed ' signal, control and regulation of the valve opening. Actuator with single-phase AC motor is equipped with (such as valve angle and straight-stroke electric actuators), but also with the executing agency for three-phase AC motor, electric devices used.
