B-Pro valves are used to control system pressure and flow. They are available in 4 sizes with capacity up to 2000 l/h. The valves are used in connection with spillback nozzles, where pressure and flow in the spillback determine the nozzle capacity. The valves are suitable for use with light and heavy oil in oil burners with spillback nozzles.
