Q-Plate Orifice plates Regulate stormwater flow

ACO Q-Plate is designed to regulate stormwater flows in projects where a vortex flow control is not the most effective solution, or where flows are greater than 100l/s.

Each unit is tailored to the specific performance requirements of the application providing optimum hydraulic efficiency within the system.

Remote access to the system can be provided by the optional bypass door and the emergency drain facility - simplifying access and removing the need for direct man access to sewer manholes.

Manufactured from grade 304 stainless steel, the unit is available as a flat or curved radius to suit manhole diameter.

The Q-plate has no limitations on design flow. For smaller flows from 2-100l/s the Q-Brake is more suitable.
