Fixed cone valves are mostly used to regulate flow from dams, clear-water reservoires, barrages or storages basins. It is also a free discharge valve that is commonly used as a turbine bypass valve, reservoir drain or continuous discharge flow control valve.Discharges of large water flow rates under high pressure conditions demands an efficient conversion of energy. Any damages  due to cavitation and any risk to the structure due to vibrations and oscillations have to be avoided. Fixed cone valve has a fixed cone with contoured ribs that eliminate the vibration problems associated with other fixed cone designs. Flow is  controlled by movement of an external stainless steel gate which has a drip tight metal to metal shut off. 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.

Fixed cone valve is composed of Actuator units, drive mechanism, welded steel construction with Nitronic 60 pads,

sleeve gate, rubber seal, Nitronic 60 seat,contour ribs and optional hood. Spray piece is supported and connected by the fixed cone and the contour ribs. There is an open section between the spray piece and the welded steel body. Sleeve gate is installed outside of the spray piece and the movement of the sleeve gate can change the free discharge (free spray) area. A hood

can be installed for some application

needs and this hood can confine the flow to a smaller area which can avoid the spray of the flow and cavitation damage to the

line. Hooded fixed cone valves are mostly used in inline installation applications. Unhooded fixed cone valves are mostly used as discharge valves to release pressure,retain pressure or control the flow in the pipe line.
