意大利先導(dǎo)式電磁閥,ODE型號21T2BV22-F
在這個電磁閥系列中必須有一個小值入口管和出口管之間的壓差確保電磁閥正常工作。
但入口之間的壓差過大和出口，與2路常開直接作用的底部無閥，
導(dǎo)致所需的力的增加打開導(dǎo)向孔，所以如果這個壓力差是大于螺線管的值
閥門已經(jīng)設(shè)計，后者可能不會重新打開均勻當線圈未通電時。
為了正確操作電磁閥，并避免隔膜的快速磨損，建議啟動閥關(guān)閉，
the latter may open even when
the coil is not energized. Proportional solenoid valves are tared
individually, at the moment of installation and inspection testing,
with the adjustment screws in the fixed core: any modification of
this taring may make the valve work in a different way with
regard to the data shown on the label.
實際流量不高于Kv（即流量通過壓力損失為1巴的閥門）。
因此，閥門打開時入口壓力應(yīng)高于1巴不宜使用具有自由出口的閥門本身，
即沒有出口限制，使壓降降至1巴的值。
此外，在設(shè)計液壓回路時，必須特別注意問題可能引起超壓，
如撕裂隔膜或水錘損壞電磁閥的其他部分。
causes a reduction in the pressure
required to open the valve: if the pressure difference between
inlet and outlet is greater than the maximum value for which the
solenoid valve has been tared,
比例直動電磁閥具有入口管和出口管。
安裝有密封墊圈的柱塞直接用于打開和關(guān)閉主孔電磁閥。
不同于只有2路常閉電磁閥兩種狀態(tài)，
開和關(guān)，比例電磁閥，in線圈中電流運行的功能可以部分打開。
On these valves, unlike the other models, the fluid shall enter
into the valve so to pass through the main orifice from the lower
side towards the higher one.
In this family of solenoid valves an increase in pressure, as with
three way solenoid valves,
