Air Consumption
The air supply connection is designed in accordance
with the NAMUR standard for installing solenoid
valves.
The bottom mounting connection is designed in ac-
cordance with the ISO5211 and DIN3337 standards
for direct mounting with valve worm gear boxes or
mounting brackets.
Each actuator is marked with air connection and bot-
tom mounting holes are marked for easy track and
distinction.
The NAMUR drive pinion and the NAMUR top mounting
connection permit direct installation of accessories such
as limit switch boxes and positioners.

Air consumption depends on air supply. Air volume and action cycle times are calculated as below:
L/Min = Air volume (opening + closing) x [Air supply (Kpa) + 101.3 / 101.3] x action cycle times (/min)
