The BMS Stormbrake is a vortex flow control device devised for flow rates ranging from 0.8 l/s to 80 l/s It is manufactured from acid resistant stainless steel (Ref 1.4404/316L) is extremely easy to install or retro-fit and is suitable for a variety of applications such as stormwater management and as part of SuDS.

What is Stormbrake Vortex Flow ?

It is activated when the hydraulic head up-stream increases, hereby causing trapped air within the vortex to restrict flow to the outer orifice. It has no moving parts and requires no external energy requirement.The continuous high-throughput opening provides a secure flow control whilst reducing the danger of blockage, to a minimum.

The BMS Stormbrake is simple to install and can be used for both new & existing applications. It is fitted with an extendable handle, which ensures that it is removable from ground level for maintenance purposes. It can easily be adapted to suit any size or shape of manhole.
