PIETRO FIORENTINI先导控制压力调节器
PIETRO FIORENTINI菲奥*操作气压调节器
迪西
Dixi是用于中低压的先导控制压力调节器。 Dixi是一个“失败关闭”监管机构，如果：
?主隔膜失效
?导向膜片失效
?没有馈送到导频环路。
这些调节器适用于以前过滤的非腐蚀性气体。

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.
