Valve actuation device
FROM:YongJia DuoLi   TIME :2011-6-13

A, according to the valve type selection of electric actuators

Type of valve quite a lot, and the working principle is different also, general with rotating disc Angle, lift the valve plate other ways to realize on-off control and electric actuators, when the first should be based on supporting the valve type selection electric actuators.

1. Angle travel electric actuators (corner < 360 degrees)

Electric actuators output shaft rotation of less than a week, that is less than 360 degrees, usually for 90 degrees is the realization of the valve open or close the process control. This kind of electric actuators according to the different methods of installation interface and classified as straight even type, base crank type two kinds.

A) even type: refers to the straight actuator output shaft and stem straight even the form of installation.

B) the base type: refers to crank output shaft through the crank and stem connection form. This kind of electric actuators used in butterfly valve, ball valve and plug valves, etc.

2. Multi-turn electric actuators (corner > 360 degrees)

Electric actuators output shaft rotation of more than a week, that is more than 360 degrees, usually takes much circle to the realization of the valve open or close the process control. This kind of electric actuators used in gate valves, globe valves, etc.

3. Straight travel (linear motion) valve actuator drives output shaft of sports for linear movement type, not turn form. This kind of electric actuators apply to single seat regulator, two-seater regulator, etc.
