= 2.4 bar and p
2
= 1.0 bar is calculated using the following formula:
Q = K
VS
x 36.22 in m³/h.
4)
The permissible control pressure with the CNOMO interface depends on the pilot valve used.
5)
The maximum permissible ambient temperature depends on the permissible ambient temperature of the compo-
nents, type of protection and temperature class.
