when the supply is given to SOV,the coil energies and moves
the plunger towards it.therefore it opens the path.

Answer / gk

in solenoid valve there is a hollow spindle in which
plunger moves whenever the supply given to coil,magnetic
field generates and the plunger will move towards the
magnetic field,the coil which mounts on the spindle of the
valve that supply may be 220 v ac or 24v dc.and also we can
check soenoid valve by manually by twist the screw.
