The electric ball valve actuator is an indispensable driving control device for program control, self-control and long-distance control of the electric ball valve. The movement process is controlled by stroke, torque and the like. Because the operating characteristics and utilization of the electric ball valve actuator depend on the type and characteristics of the ball valve, proper selection of the ball valve actuator is essential to avoid overloading.

Actuator output torque is the primary parameter for selecting an electric actuator. Secondly, according to the different operating conditions of the ball valve, the proper opening and closing speed should be selected, so as to avoid the water hammer phenomenon caused by the opening and closing speed of the ball valve actuator too fast.

Electric ball valve actuators have special requirements that must be able to limit the torsional force (axial force) and the rotating viewpoint. When the electric device standard is determined, its steering torque is also determined. Generally running in a predetermined time, the motor will not be overloaded. However, if the following conditions are presented, the overload may be caused: first, the power supply voltage is low, the required torque is not obtained, and the motor stops rolling; secondly, the torque limiting organization is set to be greater than the suspended torque. Causes excessive torque to occur in succession, causing the motor to stop rolling; Third, intermittent operation, heat accumulation occurs, exceeding the allowable temperature rise of the motor; Fourth, the torque is limited to the organization circuit for some reason, causing the torque to pass Large; the fifth is to use the ambient temperature is too high, so that the heat capacity of the motor is reduced.

1, the ambient temperature should be controlled within -25 ° C -70 ° C.

2, several conditions should be selected explosion-proof electric ball valve, current instability, environmental corrosion, flammable and explosive occasions, special media, long-term no protection.

3, because the electric organization is more complicated, when the problem is presented, it should not be disassembled by itself to avoid accidents.

4. Do not beat the electric ball valve or put the items together under any conditions.
