The microprocessor of the Fuxi intelligent adjustment locator sends switch commands to the electrical conversion module based on the deviation of the 4-20mA control signal and valve position feedback, causing a change in the output air flow and driving the valve to change its opening. When the opening reaches the required position, the piezoelectric valve has no output, stabilizing the valve at that position. $r $nCVX adopts a new piezoelectric valve principle electrical conversion technology and uses German imported electrical conversion modules; Ultra low power consumption, up to 2 billion switches, steady-state gas consumption less than 36L/h, far less than the 400L/h of conventional locators.
