Hollow-jet valves have proved their high efficiency in hydroelectric power plants and irrigation dams. They ensure a regulated and environmentally compatible outlet of water either to the outside or into underwater tanks. The water is also enriched with oxygen at the same time. Their high-quality steel construction combined with elastic/metallic sealing enables energy dissipation without cavitation.
