    The model type , installation type ,output type, output torque ,voltage, control mode, matched valves, valve material, and so on are selectable, please ask for the specific information and price. we warmly welcome your inquiry. ( If you don't know what type you need, just ask me, don't be hesitate!)     Product Description   Introduced bernard technology electric actuator quarter-turn electric actuatorAS-25, BS-60,A+RS100    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 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.   The product model establishment       For example Model A+RS output torque 1000Nm, 220V, total travel time 30S, foot mounted (plate) type, integral modulating type.           Related Products Mode    MD series  electric actuator
