External regulation electric high vacuum butterfly pneumatic valve pictures

Electric vacuum pneumatic valve regulating butterfly mainly driven by electric adjustment type device with high vacuum butterfly of pneumatic valve, by an external power supply switch ( Using manual transfer switch or computer control) Or external input signal, to implement the pneumatic valves open and close or intermediate position control, so as to put through or cut off the airflow in the vacuum line. Principle for electric actuator driven by rotary motion into the linear motion of the pneumatic valve stem, and then with the rotation of the pneumatic valve rod into a butterfly gate movement and deflection, complete the butterfly door rotation and deflection of two actions on/off.









the so-called electric butterfly vacuum pneumatic valve to the vacuum meaning, is refers to in the given space below a atmospheric pressure gas state, generally used for non-corrosive saturated water, steam and other gases. Under the vacuum sealed performance is good, high stiffness, small flow resistance, light weight small operating torque. The pneumatic valve and vacuum butterfly itself without connecting rod, also didn't bolt, making them extremely reliable to use, the corresponding also will be a long service life.






electric vacuum butterfly pneumatic valve selection of materials for high quality steel plate welding, the butterfly plate truss structure design; & adjustment sealing ring. the other T” Successful design of special structure of arc and eccentric type; Packing: take two sets of packing midplane water seal structure.
