CONFIGURATION AND FUNCTION
SWITCH TYPE ACTUATOR
A/B/G/H CONTROL CIRCUIT
The switch type only has the fully open and fully closedextreme positions. After receiving the appropriateinstruction, the actuator drives the door to the fully openand fully closed positions.
S2 working system, continuous running time does notexceed 15 minutes.
C/D CONTROL CIRCUIT
When the actuator is driving the valve, it simultaneouslyfeedbacks the valve position signal to the central controlsystem, the C-type feedback resistance valve positionsignal, and the D-type analog valve position signal.
Using S2 short-time working system, continuous runningtime does not exceed 15 minutes.
INTELLIGENT REGULATING ACTUATOR
E一TYPE CONTROL CIRCUIT
The intelligent module is placed inside the actuator,andaccording to the changes of the controlled variables(flow,pressure, temperature,liquid level) in the pipeline,it accepts the instructions of the central control system todrive the valve to the appropriate opening position.
Using s4 intermittent working system, the workingfrequency can reach 1200 times per hour.
Due to the working characteristics of the valve, theactuator of the valve is required to have full-loadstarting capability in the open,closed, and any positionin the middle.This requires the motor of the actuatorto have a high starting torque. At the same time, due tothe adjustment of flow (opening), the motor must alsohave a small moment of inertia. POE series electricactuator motors are specially designed to meet theserequirements.
When the actuator is blocked, the temperature of themotor will rise rapidly. When the motor temperature rises to 125°C, the PTC overheat protector buried in the motor windings will cut off the electrical appliances, therebyprotecting the motor and the control system. When the motor temperature drops to 90 ~105 ℃ , the circuit willresume.
