Applications
Motorised control of dampers, ball and butterfly
valves. Application in mixed air and shut-offer
damper control. For primary HVAC air-handling and
zone units.
Smoke and air isolation shut-off damper control for
ventilation systems Ball valve control for domestic
and drinking water, condensation water, air (i.e.
zone units).
The actuator 231L has digital communication
capabilities and can be networked with a LON-Bus
system. All actuators correspond to the UL, CSA &
DIN-VDE standards, CE guidelines.
