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.
For a correct operation of the solenoid valve, and to avoid a quick wear of the diaphragm, it
is advisable that, once starting the valve closing, the actual flow isn’t higher than the Kv (i.e.:
flow rate through the valve with a pressure loss of 1 bar).

每个孔都通向不同的油管，腔中间是阀，两面是两块电磁铁，
哪面的磁铁线圈通电阀体就会被吸引到哪边，通过控制阀体的移动来档住或漏出不同的排油的孔，
而进油孔是常开的，液压油就会进入不同的排油管，然后通过油的压力来推动油刚的活塞，
活塞又带动活塞杆，活塞竿带动机械装置动。这样通过控制电磁铁的电流就控制了机械运动。
In this family of solenoid valves there must be a minimum
pressure difference between the inlet pipe and the outlet one
to ensure correct functioning of the solenoid valve. However,
For this reason, should the inlet pressure when the valve is open, be higher than 1 bar, it is
not advisable the use of the valve itself with free outlet, i.e. without an outlet restriction bringing
the pressure drop to the value of 1 bar.

Moreover, particular attention must be paid in designing the hydraulic circuit to the problem of
water hammering which could cause overpressures such as to lacerate the diaphragm or
damage other parts of the solenoid valve.
