1)
The air flow rate when p
1
= 2.4 bar and p
2
= 1.0 bar is calculated using the following formula:
Q = K
VS
x 36.22 in m³/h.
2)
Emergency release or locking of compressed air supply
3) The permissible control pressure with the CNOMO interface depends on the pilot valve used.
4)
The maximum permissible ambient temperature depends on the permissible ambient temperature of the compo-
nents, type of protection and temperature class.
5)
NAMUR interface according to VDI/VDE 3845
