Corrosion-resistant versions

The round VRE volume flow regulators control volume flows constantly and variably; full shut-off is also possible.

Depending on the design, they are suitable for use in polluted/contaminated air.
Actuation and control are carried out with external energy, either electrically or pneumatically.
With push-in ends and insertion bead for a lip seal, suitable for connection to air ducts to DIN EN 1506 or EN 13180 or flanges to DIN 24154 series 1 from nominal size 500 mm. Versions:
Steel – galvanized, coated, stainless steel
PPs – for aggressive media, as all components in the air flow are made of plastic.

  • Attachment of various controller makes/components possible
  • Can be combined with spring return or high-speed drives
  • Corrosion-resistant versions available
  • With dynamic (VRE) or static (VRE-s) measuring principle
