  • Filter effluent and back wash applications or anywhere flow control is required.
  • Most often PFS supplies butterfly valves that are direct coupled to the outlet of the venturi, turning the venturi into a Rate of Flow Controller (ROFC). They are usually used on filter effluent and back wash applications where the venturi indicates the flow rate to a separate electronic controller which then tells the actuator to open or close the butterfly valve to control the flow.
