Circular damper product introduction
Circular damper is mainly used for boiler hot air way adjustment, according to distinguish between nominal diameter specifications DN100 - DN1400 18 species, etc. Circular damper in full close state leakage rate of 3% or less; The highest working pressure 50 kpa or less; The highest working temperature 400 ℃ or less.

The main performance and characteristics of circular damper
A. is applicable to coal, smoke, dust, gas and other medium; Working temperature of 450 ℃ or less
B.D D41 series circular damper has a normal and wear-resisting type which can be chosen by the user, to ensure that the requirements of different working conditions, improve the service life of the damper.
C.D D42 series party damper has six axis from uniaxial to a variety of forms for selection.
D. can use manual, worm gear and worm, such as electric transmission way.

The use of circular damper
Electric circular damper is mainly used in power plant, air duct, do the closure or adjust medium flow in flue, the air duct, flue can also be used in other industries. All round damper can make the system a pipeline medium circulation/truncate or medium flow changes according to the control. For small diameter of damper, it has the function of river closure and adjust medium flow in two, for large diameter circular damper, its regulating function is not obvious, mainly used its closure function.
Electric circular damper according to distinguish between nominal diameter, preparation of specifications set until 23 kinds of DN100-2200.
Electric throttle circle highlights for installing turbine box shell, and is equipped with guarantee fully open baffle block.
Electric circular damper using medium temperature shall not exceed 400 ℃.
Electric air door is mainly used in power plant, air duct, do the closure or adjust medium flow in flue, the air duct, flue can also be used in other industries. All round damper can make the system a pipeline medium circulation/truncate or medium flow changes according to the control. For small diameter of damper, it has the function of river closure and adjust medium flow in two, for large diameter circular damper, its linear adjustable is not obvious, mainly used its closure function.
