Electric actuator LQ model with anti-exposion ATEX.
Main structure and functions:
Motor:220V single phase motor or 380V three Phase YDF type
Speed reducer: it is composed of two class of worm and worm gear
Travel control and position direction: from the output shaft to lead out the cam shaft to make 90 degree rotation and the
limit cam can a make 90 degree rotation to contrthe travel.The position indicating plate is co-axial with the cam shaft to make 90 degree rotation and indicate the valve position.And also can provide potentiometer for remote electric signal output which is not provided normally(The user should specify when order)
Torque control unit: to control torque of the actuator.lt is composed of cams of both c1ose and open and microswitch.(LQ1 don’t have this part)
Manual override:it is semi-automation with the priority of electric operation Pull the handle and then turn the handwheel to realize manual operation. In electrically operated,switching the handle will return to electric position automatically and realize electric operation
