KTL Linear-turn Electric Actuator
Product Overview
KTL series linear-turn electric actuator is powered by AC220V or AC380V power supply, and directly accepts the signal from the control adjustment system (4-20maDC or 0-5VDC) to drive the regulating valve to achieve a predetermined linear reciprocating motion to achieve the accuracy of the valve position. Positioning, and feedback the valve position to the control system with the same analog signal, it has various action transformation functions required by the regulating valve itself, valve position signal function and manual function, suitable for switching and regulating control of linear motion valves
Main Features
1. The actuator is small in size, light in weight, and easy to operate. The built-in servo amplifier only needs to be connected to 4-20maDc or 1-5VDC) and the corresponding power signal to work.
2. The controller adopts advanced hybrid integrated circuit, which is sealed with resin and cast into a box shape, small in size and high in reliability.
3. The feedback detection of the driver adopts a high-performance conductive plastic potentiometer with a resolution of <0.4%
4. With self-diagnosis function, when a fault occurs, the indicator light on the controller will immediately send out a command signal
5. When the off signal can be set by the state selection switch (the spool is fully open, fully closed or self-locking)
6. Set forward and reverse action by state selection
7. The input signal (4-20ma or 1-5V DC) can be set with the state selection switch
8. Simple and easy adjustment of working zero point (contact point) and stroke (end point)
9. The use of synchronous belt drive effectively reduces noise
10. Instantaneous protection function When the load is rated, the state can be self-locked. When a fault occurs, the protection can be started immediately, and the delay protection can be canceled by running in the reverse direction.
