Plug Style Flow Regulator with Orifice

Plug style flow regulators are usually used to regulate storm water at the source. They are generally installed directly in the catch basins and are kept in position by their slightly conic shape and by hydrostatic pressure.

Plug style flow regulators permit storage of storm water in catch basins and surface accumulation during downpours.

Plug style flow regulators with orifice allow economical control of the maximum peak flows authorized by many municipalities.
