Lower environmental impact

The Fixed Cone Valves are mainly used in applications that require water to be freely discharged into the atmosphere at controlled rates. This type of valve dissipates enormous amounts of energy by breaking down the water into a large, hollow expanding jet.

The Fixed Cone Valves are designed to operate at variable controlled flow rates between fully open and fully closed without creating damaging vibrations.

Although the primary objective of this type of valve is for free discharge of water into the atmosphere, Fixed Cone Valves can also be used for submerged discharge operations.

In the event that site conditions require concentration of the water outflow, Vortex Hydra also design and manufacture suitable Concentration Hoods.
