Electric high vacuum butterfly valve main technical performance

Electric high-vacuum butterfly valve is the use of rotary electric, electronically-controlled valve drive stem and valve plate to perform opening and closing movements. Vacuum butterfly valve can be achieved through the external power switch (with manual index switch or computer control) or external input signal to achieve vacuum valve switch or control of the middle position, so as to achieve the purpose of turning on or off the air flow in the vacuum circuit. The body of the valve plate clamping structure, the valve plate seal clamping, except that it can be used in a vacuum state, can also be used under low pressure state. Electric high vacuum butterfly valve is used to turn on or off the airflow in the vacuum line. Electric high vacuum butterfly valve suitable medium for pure air and non-corrosive gases.
