Litostroj - Model PRV and EDS -Energy Dissipating System (EDS)

Energy dissipating system (EDS) is designed to divert the water and serves as a turbine bypass system. EDS systems can be used either as a pressure relief valve (PRV) to mitigate a penstock transient phenomenon or as a long-term energy dissipation system used for flow ramping or maintaining the flow in the penstock system when the turbines are out of operation. Litostroj Power is able to advise and design optimal PRV or EDS solutions based on the site conditions and ramping requirements. We have long tradition in design and installation of both systems, PRV as well as EDS valves. Our largest PRVs are installed on 80 MW Francis units as a penstock overpressure safety device.
