d = Seat diameter [cm]
∆p = Differential pressure across the valve
[bar]
A = Actuator diaphragm area [cm 2 ]
F = Upper bench range of the actuator
[bar]
If there are no specifications, calculate as
follows:
Required supply pressure =
Upper bench range value + 1 bar
Note!
The signal pressure at the output (Out-
put 38) of the positioner can be limited to
1.4, 2.4 or 3.7 bar over Code 16 or the
