ODE兩位兩通常閉電磁閥規(guī)格型號
功能是基本上類似于具有導控制的電磁閥
于隔膜運動除了即使用
入口和出口之間的小壓力差，起作用
通過柱塞的直接作用確保膜片。
因此，在這種情況下，當線圈不通電時在腔室上方有壓力下的流體
膜片下面有壓力只有在主孔外部的區(qū)域：
因此在隔膜上的力的結(jié)果是推動它以關閉主孔口。
2 way normally open direct acting solenoid valves have an inlet
pipe and a outlet pipe. The plunger, acting on the gasket holder
by means of a rod, provides for opening and closing the solenoid
valve. When the coil is not energized the gasket holder, under
the action of a spring, is kept in such a position that the orifice is
open, permitting fluid flow.

When the coil is energized the plunger moves downwards and,
當線圈通電時，運動其上安裝有墊圈的柱塞打開
孔在整個膜片（導孔）和放電腔室上方的隔膜。
2路常閉復合操作電磁閥具有入口管和出口管。
In this solenoid valve family an increase in pressure causes an
increase in the force required to open the valve: if the pressure
difference between inlet and outlet is greater than the maximum
value for which the valve has been designed, the latter may not
reopen even with the coil deactivated.
因此，如果閥門打開時的入口壓力，高于1巴，就是不建議使用具有自由出口的閥本身，
即沒有出口限制帶來
壓力下降到1巴的值。此外，在設計液壓回路時必須特別注意問題水錘擊可能導致過壓，
如撕裂隔膜或損壞電磁閥的其他部件。
