Spiral duct control valve Ø 125 mm

  • Guaranteed airtight
  • Simple installation


A spiro duct control valve made of galvanised steel is ideal for creating a ventilation system. Airflow is not impeded by a flat inner wall, allowing ventilation to work optimally. This steel quadrant allows the right amount of air to pass through a ventilation duct.

Thanks to the rubber seal (safe) our galvanised spiro duct control valve fulfils the high-quality airtightness class D. This control valve from Interduct is made of steel and has a diameter of Ø 125 mm. Suitable for mounting on a duct with a diameter of 125 mm.

With the spiro duct control valve, available in our product range and equipped with a rubber seal, you can configure the ventilation system exactly as required. Are you not able to find your desired product listed on our site? Inquire about our options.
