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.
