Wide range of use of fine and small electric actuators
Therefore, the torque required for valves of the same specification produced by different manufacturers are also different. Even the torque of valves of the same specification produced by the same valve manufacturer is also different. When the torque of the actuator is selected too small, the valve cannot be opened and closed normally. Therefore, the fine and small electric actuator must choose a reasonable torque range.
Determine the electrical parameters according to the selected electric actuator
Because the electrical parameters of different actuator manufacturers are different, it is generally necessary to determine the electrical parameters when designing and selecting, mainly motor power, rated current, secondary control loop voltage, etc., often negligence in this regard, as a result, the control system Mismatch with the parameters of the fine and small electric actuators causes malfunctions such as air circuit breaker tripping, fuse blown, thermal overload relay protection tripping during operation, etc.
