The working principle of electric high vacuum butterfly valve

- - - - - - - - - - - - : electric high vacuum butterfly valve is used to transform the electric, electronic adjustable valve actuation device to drive the stem and disc to perform opening and closing movements. The vacuum butterfly valve by an external power supply switch ( Using manual transfer switch or computer control) Or external input signal, to realize the control of vacuum valve switch or intermediate position, so as to put through or cut off the airflow in the vacuum line. Body of the valve plate adopts clamping structure, the valve plate seal clamp, in addition to use under vacuum condition, can also be used in low pressure state. Electric high vacuum butterfly valve is used to connect or cut off the airflow in the vacuum line. Electric high vacuum butterfly valve applicable medium for pure air and noncorrosive gases. Electric high vacuum butterfly valve main parts material valve body, valve cover, stem carbon steel or stainless steel vacuum valve seal nitrile rubber, fluorine rubber. Electric high vacuum butterfly valve scope to the main technical performance. × - - - - - - Pa valve leakage rate & le; 。 × - - - - - - Pa.
