Oriflo Flow Control Chambers for managing surface water flows on site
Oriflo Flow Control systems are a range of orifice plate flow control chambers, designed to support SuDS Management and the sewer infrastructure as part of a designed attenuation system, helping prevent flooding by controlling the flow into the main sewer.
The use of orifice plate flow control chambers has proven to reduce the land requirement and make significant savings on the the cost of larger flow control units and chambers at the final outfall of the site and the use of strategically sited Oriflo units can help optimise SuDS.
We manufacture two designs of Oriflo – P Series (Unprotected Plate) and C Series (Protected Plate).
Oriflo P Series (Unprotected Plate)
Designed to be used where silt and debris has already been removed upstream and there is little chance that the orifice could be blocked. The P series is ideal for installation in cellular/crate type attenuation and from permeable paving.

Product code: OFCP300
Flow Control Chamber for use with 110/160mm EN 1401 pipework

Flow Control Chamber for use with 160mm EN 1401 & 225/300mm twinwall pipework
Product code: OFCP600
Flow Control Chamber for use with various pipework diameters from 110mm EN 1401 to 450mm twinwall
Product code: OFCP1050
Oriflo C Series (Protected Plate)
Designed to be used downstream of open type attenuation schemes like basins, swales and large oversized pipes, where silt and debris could be flushed into the chamber during rainfall and storm conditions. The C Series range all have a protective SILTBLOK screen wall, that protects the orifice itself from blockage. The SILTBLOK technology allows water to flow through the screen freely but filters out silt and debris.
