1. Select the actuator according to the type of valve: multi-turn, part-turn direct connection type, straight stroke, part-turn angle stroke;
2. Control mode: switch type, adjustable type;
3. Maximum torque value;
4.IP protection level
5.Working voltage
6. Configuration: Basic type (requires additional control box) or integral type (with local control, integrated control box) or intelligent integration (with LCD display, remote control, etc.)
Determine electrical parameters based on selected electric actuator
Because the electrical parameters of different actuator manufacturers are different, generally the electrical parameters need to be determined when designing and selecting, mainly including motor power, rated current, secondary control loop voltage, etc., often negligent in this regard, resulting in control systems Mismatches with electric actuator parameters cause faults such as air-open tripping, fuse blowing, and thermal overload relay protection tripping during operation.
