valve electric actuators

Detailed Product Description

SD Series Electric Actuator ,(valve electric actuators:)

1. Input signal: 4 mA ~ 20 mA direct-current obtain 1 V ~ 5 V direct-current; 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 3. Input the passage number: 1 (discrete is 3) 4. Fundamental error: +- 0.5%; +- 1%; =- 2.5%; 5. Time is bad: 0.5%; 1%; 1.5%; 6. Blind spot: 0.5% ~ 3%; 7. Damp characteristic property: There be no swing 8. Mains input: 220 single-phase V + 10% 50 Hz =- 1% -20% 380 triphase V +- 10% 50 HZ +- 1% 9. Work environment: Temperature: -85 30 degree ~ + of degree Humidity: Around being equal or less than 95%, air do not contain have corrosivity matter 10. Surgery protects a grade: Accord with GB4208IP65; IP67; IP68 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 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) 13. Development electricity braking function; 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) 15. Character of service: The reversible intermittent character of service, on continue leading 50%, time of 1200 per hour of on number of times.
