Advantages of the A+Z,B+Z linear actuator
  High pointing accuracy integrated product
 This product output corner pint pointing ,the overall proportional control the amplifier ,the position transmission function concentrates in together ,Realizes the true integration ,Receives the 4-20mA signal ,Outputs the 4-20mA signal.
 
 Bidirectional moment of force protection function
 Namely when valve in normal work process , Because the accidental reason creates the valve deactivation ,And causes in the situation which the electrical machinery stops up transfers ,This actuator immediately automatic turnoff power source ,Electrical machinery because of power failure but knock off ,Thus the protection main engine equipment is not damaged.
 
 The introduced new generation of intelligent model
Assembled and manufactured in domestic, SD series introduce the advanced technology from France and the key components are imported from the country of origin. The manufacturing process is strictly in accord with the technique requirements of French company. However, the series mentioned above is produced with higher quality and lower cost.
With the compact structure, light weight, fully function, over 1200 times per hour of the starting times and great logic control circuit, this series is especially applied to the conditions of high-efficient automation and frequent movements.
 
Cut-off signal protection
The actuator stop at the original, all-on or all-off position which is instructed by users as the signal is interrupted by accident or the input signal is less than 3mA (called the cut-off signal) in order to guarantee the whole system's safe and stable. It also possesses the output connection point for alarm.
 
Over-torque of two- way protecting function
The actuator has an over-torque surveying device that can accurately survey the torque of the valve. When the torque exceeds the setting scope, the torque switches inside the actuator and outputs a signal to the controlling circuit for stopping the motor to protect the valve, the driving parts and the motor. After the mechanical over-torque fault is relieved, shutting down the power supply or input an instantaneously reversed signal, the actuator will come back to turn normally.
 
Auto switch function
The actuator can implement three kinds of switch function - "Distant- automatic / distant -manual /local". It can also operate electrically and manually on the spot.
The pros and cons of switch function
The control panel program has the pros and cons of switch function that satisfied different situations on-the-spot.
 
Dynamic braking
The control panel program of modulating model electric actuator has the dynamic braking function that can prevent motor's inertia movement and ensure the stability and reliability of the controlling system.
 
Servo-motor with double protection and high-efficiency
 
All the motor has the thermal and open-phase protecting function. When there is an unexpected failure, it will shut off the power supply effectively so as to protect the motor. It serves as a good servo characteristic and it will not overheat after frequent movements.
 
Stronger anti-interference function
With the imported main chip of control panel and stable performance, the actuator has the stronger anti-interference capability. The input and output signal adopt the shielded wire.
