Fourth, large differential pressure is allowed. The withstand voltage difference of the electric switch butterfly valve can reach more than 1.0MPa. With the help of DDS switch debugging technology, the switch debugging can be carried out directly, which is different from the original electric valve and simplifies the debugging steps.
