90A 95A 7AI 11AI Electric actuator

Overview of 90A 95A 7AI 11AI Electric actuator

The valve electric device can be divided into two series: controllable type and simple type. Their mechanical structures are completely the same, both of which are based on the multi turn type. With worm gear and worm reducer, the valve electric device can be connected into a four turn output. The main difference between the two series is in the electrical part. Controllable type with electrical control box, with AC contactor, main control board, etc. installed inside. When three-phase 380VAC power supply is provided, the electric head can be operated. The simple type can only be operated after the terminal board is additionally equipped with AC contactor and other components.

Main technical parameters and protection functions:

1. Simple technical parameters

(1) Ambient temperature: - 30 ℃~± 70 ℃

(2) Protection grade: IP68 (equivalent to 48 hours in 3m water depth)

(3) Power supply: three-phase 380V AC ± 10% 50Hz 60Hz

(4) Relative humidity: 95%

(5) Action frequency: 600 times per hour, and the continuous working time is less than 15 minutes per hour.

2. Controllable technical parameters

(l) 0~5mA, 0~10mA, 4~20mA, 0~50mA, 0~5V, 0~10V

0~20V DC current. The voltage is used as the control signal.

Note: controllable type has various technical parameters of simple type.

3. Protection function

(1) Automatic phase correction (2) Phase loss protection (3) Photoelectric isolator (4) Instantaneous reversing protection (5) Emergency control (E. S. D) (6) Valve stuck protection (7) Hammer protection (8) Motor overheating protection
