Cone Jet Valves

Cone jet valves are used in dam bottom outlets for energy dissipation. The valves feature cavitation-free operation over a wide control range and allow energy dissipation of large flows and heads with simultaneous oxygen enrichment of the water. Cone jet valves are mainly steel-welded and are actuated either hydraulically or electromechanically.

Penstock - Safety Valves

Penstock safety valves are installed at the bottom of dams, before the penstock. They have the task of shutting-off the flow of water if the penstock leading down to the valley is destroyed or damaged as a result of material fatigue, uncontrolled earth movements or sabotage.
