Fixed Cone Valves are used to regulate flow from dams and reservoirs. It is a free discharge valve that is commonly used as a turbine bypass valve, reservoir drain, or continuous discharge flow control valve. Flow is controlled by movement of an external stainless steel gate which has a drip tight metal-to-metal shut off against the seat. When discharging into the atmosphere, the jet spreads out in a wide cone angle and breaks up into a fine spray. If containment of the jet is desired, a hood can be installed which concentrates the flow.

Sleeve Valves are used to reduce and regulate pressure and control flow. Designed specifically to dissipate energy, the Sleeve Valve controls the point of cavitation, but does not eliminate cavitation completely. The stainless steel sleeve and innovative nozzle pattern balance the fluid forces in the valve. The water jets strike each other instead of the valve walls preventing damage.
