VTLPBUF01 pneumatic high vacuum butterfly valve uses solenoid directional valve to change the direction of air passage and controls the actuating cylinder to drive the butterfly valve opened and closed. It is used to put through or cut off the airflow in vacuum pileline. Applicable medium can be pure air and noncorrosive gases. They may be fitted with signal feedback device and electropneumatic valve positioner.
