A+Z100K/F Linear Control Valve Electric Actuator

A+Z series linear-turn electric actuator

The linear-turn actuator outputs push-pull force and linear displacement. Mainly used for single and double seat regulating valve, sleeve valve, etc.

Brief introduction

The linear-turn device works with various types of multi-tum actuators to form linear-turn electrical actuator for various applications, 

such as ST6+VE50S, T14+VE200S. etc. 

For details, please refer to next pages. In selecting parameters for electrical actuators, please follow the formula below:

       Actuator torque = operating thrust x moment/thrust

       Full-stroke cycles = Max. stroke x cycle/stroke

       Operating time = 60x cycles/actuator speed (rpm)

Diversity function

1. Over torque protection: The actuator has an over-torque protection measuring mechanism, which can accurately measure the acting force of the valve. When the acting torque exceeds the range, the over-torque switch will act, and the control circuit will stop the operation of the direction and output the signal. When the motor stops, the valve and the actuator will be protected. 

2. Motor overheat protection: There is a thermal relay inside the motor, and the motor will automatically cut off the power supply when the motor is abnormally overheat.

3. Electrical protection: The input and output channels are all optically isolated.

4. Limit protection: The valve position is detected by a precision potentiometer, and four independently adjustable cams are installed on the mechanism to to control the upper and lower limit positions of the actuator.

5. Off signal protection: The regulating actuator has a signal detection circuit. If the input or output is disconnected, the actuator can keep its original flavor and run to the fully closed or fully open emergency position.

6. Off power protection: The SE actuator is mechanically self-locking, and the actuator stops in place in the event of a power failure.

7.  Hand：wheel operation: Drive handwheel provides emergency manual operation in the event of power failure or actuator failure.

8. Electric braking function: The modulating actuator has the function of electric braking to prevent the impact on the valve when the motor inertia is too large and improve the control accuracy.

9. High torque low inertia motor: Single-phase or three-phase fully enclosed squirrel-cage induction motors with high starting torque, low rotational inertia and small starting current are used.

10. Position indicator: The position indicates that the output current is 4~20mADC. Output impedance ≦75Ω, constant current output.
