burkert 0280電磁閥 is a normally closed or normally open servo-assisted solenoid valve (circuit functions A and B). For circuit function A, burkert 0280電磁閥 is normally closed by spring action assisted by the fluid pressure. When de-energized, a pressure is built up above the servo diaphragm pressing it down to close the valve. When energized, the space above the servo diaphragm is exhausted via the pilot valve, the diaphragm is lifted by the fluid pressure to open the valve.
