Quarter-turn intelligent integration electric actuator can be used to control various valves with a regulating

 angle of 0-90° and the torque range is: 35-10000Nm. It can used for control all of quarter-turn valve like: 

flue cut-off gate, boiler’s primary and secondary wind, boiler’s side wind, air pre-heater inlet and outlet 

damper regulator, butterfly valve, ball valve, louver valve, damper, plug valve, flapper valve, etc. 

Explosion-proof Grade: IP67, IP68.

SQ100,SQ200,SQ400 SQ600 intelligent electric actuator has archieved an excellent reputation over the 

years in this market thanks to a range of actuators providing the following features:

Compact construction with a high output torque 

Self-locking gear train to maintain the position of the valve when the actuator is de-energized

Very good resistance to vibrations

Very simple settings - no specific tool required

Adjustable mechanical travel limit stops to prevent overtravel

Removable drive socket for easy machining

Emergency handwheel and mechanical position indicator provided on all actuators as a standard

Single phase power 220v, 50Hz

Three phase power 380v, 50Hz

       SQ100 foot-plate mounted                               SQ200,SQ400 foot-pate mounted

1. Easy limit adjustment

2. Self-locking at all speeds

3. Continuous gear transmission between motor and valve

4. Excellent vibration resistance on main mechanical components

5. No regular maintain required, gear lubrication is effective throughout its service life

6. High gear system efficiency and low wear

7. High performance and low noise

Hand wheel does not rotate during electrical control; automatic manual and motor operation switching.
