Butterfly Damper with Sealing System


Butterfly damper with sealing system includes two butterflies. And seal is made in the area between these two discs, injecting close air at a very high pressure. The system appoints a pressurized chamber that ensures valves air-tightness on the conduit. Limited to conduit pressures less than 250 mm of water column, this system makes sure the air tightness of the valve. It is made up of a sealing valve, a dilation compensator, an electro-ventilator and a sealing pipe.

The system has the following actuators:

 

  • On/Off Pneumatic Actuator
  • Electric Actuator
  • Pneumatic Actuator With Regulation

Insulation: The valves are equipped for an outer insulation of 200 mm. A sufficient space is left free, in order to change the bearings and packing in future without removal of the insulation.
