CLEVEDON, U.K. - Hydro International is pleased to announce that its pioneering `STH` range Hydro-Brake® Flow Control product has been granted BBA (British Board of Agrément) Certification. This is a significant and important achievement, strengthening the company`s status as the leading provider of vortex and complementary technologies to the water sector.

"Obtaining BBA Certification is an exciting milestone for Hydro International, formally confirming the ability of the STH to perform to within plus or minus 5% of specification" said Dr Mike Faram, Hydro International's Group Technical Manager.

"This forms part of a wider initiative to highlight the importance of appropriately defining requirements when specifying vortex flow controls. Historically, design engineers have tended to design on full characteristics, but then provide only single point specifications on technical schedules. This means that when a drainage scheme is implemented, it is possible that a flow control other than that modelled in design may be used. This can lead to adverse effects, including inefficient system operation and increased potential for flooding. The solution to this is very simple; drainage engineers should provide multiple-point criteria in their specifications, information that is supplied as standard with every Hydro-Brake® quotation. They should also specify independently certified products where available."

Hydro-Brake® Flow Controls operate by inducing vortex motion in a drainage system flow, thereby slowing it down and preventing downstream flooding. They offer greater resilience to blockage and opportunities for optimised drainage system design and operation compared to other types of flow control.

The certification, which covers hydraulic performance as well as manufacturing and production standards, is the first of its kind to be granted for a vortex flow control, confirming the superior accuracy and quality of the product.
