pressure difference between the inlet pipe and the outlet one
to ensure correct functioning of the solenoid valve. However,
main orifice: thus the resultant of the forces on the diaphragm
is such as to push it and close the main orifice. When the coil
is energized, movement of the plunger, on which a gasket is
mounted, causes opening of the pilot orifice and discharging
of the chamber above the diaphragm: the pressure unbalance
moves the diaphragm which opens the main orifice.
In this family of solenoid valves there must be a minimum
an excessive pressure difference between inlet and outlet, as
with 2 way normally closed direct acting solenoid valves,
causes an increase in the force required to open the pilot orifice,
so if this pressure difference is greater than the maximum
value for which the solenoid valve has been designed,
the latter may not open even when the coil is energized.
2 way normally closed solenoid valves with pilot control have
an inlet pipe and a outlet pipe. The main orifice, in the body,
is opened by the effect of an unbalance in pressure between
the upper and lower surfaces of a diaphragm (or piston):
