First, the working principle
T968Y electric intelligent control valve is composed of electric actuator and hydrophobic control valve of two parts. Electric control valve input is sent to the regulator DC signal amplified by the servo amplifier to drive the implementing agency, resulting in axial thrust, driven by regulating valve action, causing changes in media flow to regulate various parameters in the system. At the same time, the actuator sends a valve position signal for servo amplifier comparison, so that the control valve always remains in an input signal corresponding position to complete the servo adjustment task.
