Flow Control Chamber

  •  FP McCann Precast Concrete Drainage Flow Control Chamber
FP McCann Flow Control Chamber Installation
 
The FP McCann Easi-Flow chamber combines an integral base and side walls with provision for inlet and outlet connections. It can be used in a number of applications, including:
  • As a silt-trap
  • As a valve chamber
  • As a flow rate controller (requires installation of a vortex valve unit, sold separately).
Sizes available:
 
Flow Control Chambers are available between DN1200 - DN3000.                                           
 
 
 
 
               
Flow rate control
FP McCann can offer supply of a StormBrake™ vortex flow control device. The StormBrake™ is designed to limit storm water outflow to a specific discharge rate. Sizes are available between 1–80 l/s depending on head height. The unit is self activating with no need for an external power source and comes with a certified flow rate.
 
The StormBrake™ is a device for controlling storm water flow by hydraulic effect without requiring moving parts. At low flow rates, water entering through the inlet passes through the vortex chamber to the outlet with no restriction. As flow rate increases water enters through the inlet with enough energy to create a vortex in the vortex chamber which results in a considerable pressure drop between the inlet and the outlet restricting the flow to the allowable discharge. The StormBrake™ therefore operates automatically with no moving parts and no external power source. A typical application of this valve is to control the flow from storm water attenuation tanks preventing downstream flooding during periods of heavy rainfall.
 
The StormBrake™ are custom designed to achieve a specified design flow rate at a given head height. They are manufactured under an ISO 9001 quality assurance system and are available in sizes compatible with the FP McCann Flow Control Chamber range.
