      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):
