These actuators are a revolution for safety,
control and shut-off dampers, VAV systems, ball valves, throttle
valves and other motorized applications for HVAC systems, in
chemical, pharmaceutical, industrial and Offshore-/Onshore plants
for use in EEx-areas zone 1, 2 (gas) and zone 21, 22 (dust).
Highest protection class (ATEX) and IP66
protection, small dimensions, only 3.5 kg weight, universal
functions and technical data, an integrated heater and optional
stainless steel housing guarantee safe operation even under
difficult environmental conditions. High quality brushless motors
guarantee long life.
All actuators are programmable and adjustable
on site. Special tools or equipment are not required. 5 motor
running times and 2 torques as well as 2 spring return times,
according to the actuator type, are selectable or adjustable on
site. The integrated universal power supply is self adaptable to
input voltages in the range of 24 to 230 VAC / DC.
The actuators are 100% overload protected and
self locking.
The F-actuators
are equipped with spring return fail safe function.
Standard shaft connection is a double squared
direct coupling with 12 × 12 mm.
Different accessories are available to adapt aux.
switches, terminal boxes or adaptations for ball valves and throttle
valves.
