Flow control plate
This plate is used in vertical stacking for exhaust air flow con
trol in ducts (3) and (5) in order to adjust the speed of the
corresponding actuator.
Vertical pressure shut−off plate
This plate can be used to cut off the corresponding valve in
vertical stacking from the terminal's operating and pilot pres
sure. Both duct (1) and duct (14) are shut off at the same
time. This means that the valve can be removed without shut
ting off the pressure.
When operating a valve terminal with a pressure shut−off
plate, pay attention to the note in Chapter 3, Section 3.3.2.
Vertical pressure supply plate
This plate can be used to supply a valve in vertical stacking
with an individual operating pressure independently of the
operating pressure of the terminal.
