SKD series electric actuator is especially designed for the cement industry. This product is the terminal performing unit based on the SD electric actuator adopting the advanced automatic modulating technology from BERNARD Company of France. It incepts 4~20 mA analogue signal from the modulator or the computer, outputs the torque the thrust and automatically operates the actuator to perform the automatic modulating.

 Main technical specifications and characteristics

1. Voltage of the power supply: 380V50HZ

  Controlling voltage: 220 V50HZ

2. Input controlling signal: 4~20 mA DC Ri=250Ω

3. Output valve position signal: 4~20 mA DC RLmax=300Ω

4. Output torque: refer to sheet 1(or sheet 2 or sheet 3)

5. The actuator and controlling box are assembled separately in order to adapt the effect of the over-high environment temperature.

6. Requirement of control mode: automatically modulate to stop at the terminal 34° and alarm. If it is necessary to modulate for the ending position, it can be startup forcefully to the ending position to guarantee the security of the equipment.

7. environment temperature:10°C~55°C

  Humidity: ≤85% no corrosive characteristic exist in the ambient air

8. Protection class: accordance with IEC145 IP65
