VALVE FOR FOUNTAIN SOLUTION

摘要

An electromagnetic valve (100) for controlling flow of a pressurized liquid, comprises a plunger (110), which is able to move from a closed, downstream position, in which an end of the plunger (110) contacts a valve seat (120), to an open upstream position, in which the plunger (110) does not contact the valve seat (120). Hence an opening is left open for fluid flow, wherein the movement of the plunger to the open position is controlled by energizing a first coil (140). A second coil (130) arranged to pull the plunger (110) towards the closed position upon energizing.
