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)
The permissible ambient temperature of the solenoid valve depends on the permissible ambient temperature of the
components, type of protection and temperature class.
3)
NAMUR interface according to VDI/VDE 3845
