Solenoid valve, type EV310A
2 Functions
2.1 Function, NC / NC MAN
Coil voltage disconnected (closed):
When the voltage to the coil (4) is disconnected, the armature (2) with the valve plates (3) is pressed down by the
closing spring (1) and closes the connection between P and A. At the same time, the connection between gates A
and R is opened. The connection between P and A will be closed for as long as the voltage to the coil is
disconnected.
Coil voltage connected (open):
When voltage is applied, the armature (2) with the valve plates (3) is lifted and closes the connection between A and
R. At the same time, the connection between P and A is opened. The connection between P and A will be open for
as long as there is voltage to the coil.
2.2 Function, NO
Coil voltage disconnected (open):
When the voltage is disconnected, the armature (2) with the valve plates (3) is pressed down by the opening spring
(1) and closes the connection between A and R. At the same time, the connection between P and A is open. The
connection between P and A will be open for as long as the voltage to the coil is disconnected.
Coil voltage connected (closed):
When voltage is applied to the coil (4), the armature (2) with the valve plates (3) is lifted and closes the connection
between P and A. At the same time, the connection between gates A and R is opened.
The connection between P and A will be closed for as long as there is voltage to the coil.
