Coil voltage disconnected (Closed)
When voltage is disconnected, the armature
spring (2) presses the armature (3) down against
the pilot orifice (4). Pressure builds up over the
diaphragm (5) via the equalizing orifice (6). The
diaphragm closes the main orifice (7) as soon as
the pressure over the diaphragm equals the inlet
pressure. The valve stays closed for as long as
voltage remains disconnected.
Coil voltage connected (open)
When voltage is applied to the coil (1), the pilot
orifice (4) is opened. Since the pilot orifice is
larger than the equalizing orifice (6), pressure
over the diaphragm (5) falls and the diaphragm
is lifted clear of the main orifice (7). The valve
stays open for as long as the required minimum
differential pressure is present and voltage is
applied to the coil.

6 Main orifice
7 Equalizing orifice
Coil voltage disconnected (open):
When the voltage to the coil (1) is disconnected,
the pilot orifice (4) is open. As the pilot orifice is
larger than the equalizing orifice (7), the pressure
across the diaphragm (5) drops and therefore it
is lifted clear of the main orifice (6). The valve will
be open for as long as the minimum differential
pressure across the valve is maintained, and for as
long as the voltage to the coil is disconnected.
Coil voltage connected (closed):
When voltage is applied to the coil (1), the valve
plate (3) is pressed down against the pilot orifice
(4). The pressure across the diaphragm (5) is built
up via the equalizing orifice (7). The diaphragm
closes the main orifice (6) as soon as the pressure
across the diaphragm is equivalent to the inlet
pressure. The valve will be closed for as long as
there is voltage to the coil.
