BC-3312 way solenoid valve
NC-function, servo-operated blocking valve
While not energised, the medium pressure is built up on the upside of the diaphragm through a pilot hole. The valve stays closed.
When energised, the pilot valve opens, a pilot hole is beeing unclosed. Through that pilot hole, the pressure above the diaphragm is released. The medium pressure lifts the diaphragm. The valve opens
