CB DOUBLE VALVE SYSTEM



The “tight-sealing/cold-insulated” CB double valve system has been developed to counter the formation of condensation or the heat bridge in living areas / to ensure that the cold air doesn’t even reach the living space when the valves are closed.



  • Both valves have an integrated silicone seal for increased tightness 
  • Stationary air layer between the double valves has an insulating effect
  • Cold insulation of the double valve module using the plastic ring
  • Valves driven by double rod
  • Double valve module made of stainless steel
  • Material transitions sealed with silicone
  • Installation by core drilling 180–200mm
    (when using external wall)


The insulating valve between
“hot and cold”

 

 

Tight-sealing – cold-insulated

 

 

Effectively prevents condensate and energy loss



THE COMPONENTS IN OVERVIEW:

Double valve module

(incl. 2 x silicone seal, stainless steel double valve handle)

PVC plastic tube 

Length 43 cm – can be cut to any length for use as a wall duct (outside diameter 170 mm, wall thickness 3 mm)

Stainless steel outside air grille

Stainless steel outside air grill which can be inspected, incl. insect protection grille and drip edge

Adapter for
square/shaft/motor control



WITHOUT VALVE

The combustion air line becomes too cold. 

Part or all of the stove system becomes too cold.

SINGLE VALVE

Part of the combustion air line becomes too cold.

DOUBLE VALVE

No risk of cooling of the combustion air line and stove system.
