First, the working principle
       T968Y electric intelligent regulating valve is composed of electric actuator and hydrophobic regulating valve. The electric regulating valve input is a DC signal sent by the regulator. After being amplified by the servo amplifier, the actuator is driven to generate an axial thrust, which drives the regulating valve to act, thereby causing a change in the medium flow rate to adjust various parameters in the system. At the same time, the actuator sends a position signal of the valve for comparison by the servo amplifier, so that the regulating valve is always maintained at a position corresponding to an input signal, and the servo adjustment task is completed.
