Dixi是用于中低壓的先導(dǎo)控制壓力調(diào)節(jié)器。 Dixi是一個(gè)“失敗關(guān)閉”監(jiān)管機(jī)構(gòu)，如果：
?主隔膜失效
?導(dǎo)向膜片失效
?沒(méi)有饋送到導(dǎo)頻環(huán)路。
這些調(diào)節(jié)器適用于以前過(guò)濾的非腐蝕性氣體。

DETERMINATION FOR THE CHOICE OF REGULATOR
It is essential to know that the flowrate capcity of a regulator is not
determined by the diameter ist attachments but by the quantity of
the pressure drop.
In order to determine the choice of regulator you must know these
three key values:
-Inlet pressure Pe -Outlet pressure Pas -Flowrate V
The flowrate values shown in the diagram have been detemined
with a more unfavourable pressure drop.
