Electric valve positioner
·Overview
The CCCX4000 series electrical valve positioner is used in conjunction with pneumatic actuators. It converts a 4-20DC mA DC current signal into an output air pressure to control the action of the actuator. At the same time, feedback is provided based on the displacement stroke of the actuator, so that the position of the valve can be correctly positioned according to the control signal output by the regulator.
CCCX4121 is used for single acting (spring return) pneumatic actuators and CCCX4122 double acting pneumatic actuators. ·Main technical parameters
