Drainage solutions: Flow Controls

Flow control products

Most products are low-maintenance and come available with easy remote access and are self-activating, removing the need for a power source. Modern-day flow control products can be tailored to individual specifications by taking into account head height and l/s restrictions.

 

Eliminating the hassle

We are able to supply a range of flow control products to suit all specifications; including units made with curved backs to eliminate the hassle of having to allocate extra space and labour accommodating standard flat-backed products.

 

We supply products from ACO, JFC Civils and Crown Water Systems.

Q-Brake Vortex

Unlike more conventional methods, ACO Q-Brake Vortex is less prone to blockage. This is due to the vortex flow control system incorporating an outlet orifice which can be 3-6 times greater than the cross sectional area of an equivalent conventional orifice plate. A larger orifice in a Q-Brake Vortex therefore facilitates greater flows through the unit when the upstream head of water is low.

  • Rate: 2-100 litres per second
  • Individually configured to suit performance criteria
  • Flexible fitting options, custom built to suit the profile of the chamber
  • Remote access bypass door
  • Available with a curved back
