Valve exploiting the principle of a side channel turbine
EPJ Web of Conferences, 2017 The article deals with a side channel turbine, which can be used as a suitable substitute for a pressure reducing valve. Reducing valves are a source of hydraulic losses. The aim is to replace them by a side channel turbine.
