valve actuator

15. Character of service: The reversible intermittent character of service, on continue leading 50%, time of 1200 per hour of on number of times.

14. Upper limit and position-limit function of lower limit: Within fixed route or distance of travel range, the upper lower limit but adjustment range controls in 40%; (The mechanical part parade Cheng gauge tap and machinery are position-limit)

13. Development electricity braking function;

12 The fault stream protects a function: To different type model,protect electric current value adjustment; (The mechanical part had had force moment to protect a switch)

11. The short signal protects a function: In advance be placed in way has three kinds: a. original place  b .all opening  c. all closes

10. Surgery protects a grade: Accord with GB4208IP65; IP67; IP68

9. Work environment: Temperature: -85 30 degree ~ + of degree Humidity: Around being equal or less than 95%, air do not contain have corrosivity matter

8. Mains input: 220 single-phase V + 10% 50 Hz =- 1% -20% 380 triphase V +- 10% 50 HZ +- 1%

7. Damp characteristic property: There be no swing

6. Blind spot: 0.5% ~ 3%;

5. Time is bad: 0.5%; 1%; 1.5%;

4. Fundamental error: +- 0.5%; +- 1%; =- 2.5%;

3. Input the passage number: 1 (discrete is 3)

2. Carries out the implement 4 ~ 20 mADC outputs signal of the change proportionality exporting a corner. The maximal signal is loaded with 0 ~ 500

1. Input signal: 4 mA ~ 20 mA direct-current obtain 1 V ~ 5 V direct-current;

valve actuator:

valve actuator:
1 .Open/close time:10 - 100 sec
2. AC 220V/380V connect with valve 1'' to 24''
3. Torque: 100-20000Nm
