Wastewater Management

Valves and actuators are essential components within wastewater management. They are responsible for controlling the flow of raw and treated water, as well as sewage through treatment and distribution networks. Valves and actuators regulate pressure and direction of flow at each stage of the management process, from the initial intake to disinfection and discharge. These components help different facilities meet the strict environmental and safety standards established by state Environment Protection Authorities (EPAs).
