FP McCann introduces the StormBrake Flow Control System

FP McCann introduces the StormBrake Flow Control System

Vortex Flow Controls (VFCs) are commonly used in drainage schemes to regulate the stormwater runoff from urban areas. Through the use of vortex flow technology, FP McCann’s WRC Approved StormBrake provides solutions to a variety of stormwater management problems. These include accurately controlling stormwater flow, minimising upstream storage requirements and reducing the risk of blockages compared to traditional orifice plates.

What is Vortex Flow Technology?

Vortex flow technology is based on the the hydrodynamic principles of swirling vortex flows. Under sufficiently high upstream water levels, a vortex is induced in the flow by the device. The vortex motion results in significant energy loss, creating a pressure drop across the device and restricting the discharge leaving the outlet. The geometric properties of the device control the amount of flow restriction and can be tailored to suit the design conditions for a specific site.

Benefits

• Minimal maintenance required after installation. FP McCann’s StormBrake™ is self-activating and functions without any mechanical components
• Outlet areas of up to 6 times larger than an equivalent orifice plate, significantly reducing the risk of blockages and the associated maintenance costs
• Reduces the amount of upstream storage required, minimising the cost of providing attenuation facilities
• Accurately designed to meet a wide range of design conditions: flows between 3 – 40 l/s; heads between 0.5 – 2.0 m. For design conditions outside of this range, please contact FP McCann directly
• Contains a bypass door which can be manually opened at ground level using a pull cable to allow easy access for inspection or blockage removal
• Provides minimal flow restriction at low upstream heads to allow fast discharge of water during the initial stages of a storm
