Product views and applications
Safety damper Ball valve
Description
The ExMax 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 Ex-areas zone 1, 2 (gas) and
zone 21, 22 (dust).
Highest protection class (ATEX) and IP66 protection, small dimensions,
only 9,5 kg weight, universal functions and technical data, an integrated
heater and an 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. Motor running times and torques as well as
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...240 VAC/DC. Furthermore it is
possible to perform control signal inverting and compulsion control by
certain connections. The actuators are 100 % overload protected.
...Max-...-YF actuators are equipped with spring return fail safe function.
Standard shaft connection is a double square direct coupling with
16 × 16 mm.
Different accessories are available to adapt auxiliary switches, terminal
boxes or adaptions for ball valves and throttle valves and other armatures.
