Guillotine gates are used in flue and duct systems, where positive shut-off isolation is necessary.

They are usually on/off type, [i.e.] completely open or completely closed, and do not regulate flow.

They provide 99% airtightness.


The damper actuators can be the on/off type or regulation type to which a positioner/position transmitter may be added.

Wheel and gearbox: suitable for the low levels of automation and for small-sized dampers.

Pneumatic cylinder: (single or double-acting). 

Electric: electric motor with gearbox, with a manual wheel for an emergency override.
