x 36.22 in
m³/h.
2)
Emergency release or locking of compressed air supply
3) With internal pilot supply
4)
With external pilot supply
5) The permissible ambient temperature of the solenoid valve depends on the permissible ambient temperature of the
components, type of protection and temperature class.
6) NAMUR interface according to VDI/VDE 3845
