Q-Brake Vortex controlling the release of stormwater

ACO Q-Brake Vortex is a horizontal vortex flow control designed to prevent downstream flooding by controlling the release of stormwater before it discharges into the watercourse or sewer. Available as a model in both microdrainage & causeway flow hydraulic design software it has many water authority approvals.

  • Custom built to suit the site requirements
  • Available from 2-100 l/s and up to 3m design head
  • Manufactured from grade 304 stainless steel
  • All parts welded to BS 4872
  • Available with curved or flat back
  • Attenuation volume required reduced
  • Larger clear opening, than traditional orifice plates, reduces risk of blockage
