Vacuum butterfly valve has high flow conductivity for turn on or cut off the vacuum airflow. The applicable media is air and non-corrosive gas. In order to get the control automatically. It operated by compressed air and through electromagnetic device to change the airflow control the actuator rotated then drive the valve open or closed.
Series - -
Actuator can be double acting and single-acting spring return type, also can driven intelligent positioner through the external input signal to control the pneumatic driving.
Design Features
