Fixed Cone Valve (Howell-Bunger type) for Dams and reservoirs.

At PARAVALVES, every product is carefully engineered as all the neccesary parameters are studied to develop our solid and reliable fixed cone valves (Howell-Bunger type).

Fixed Cone valves are made as a welded assembly construction and usually made for bottom of dams and reservoirs for water level control applications as well as a turbine bypass valve in hydroelectric power stations. It’s mainly designed to control the amount of water downstream in order not to damage the enviroment. This type of valve discharges the flow directly to the atmosphere for energy dissipation as a hollow cone shaped jet.

PARAVALVES design has a fixed cone with contoured ribs that eliminate the vibration problems and also the design includes bronze machined guides for a perfect and smooth guidance between the body and the sleeve. The Flow discharge coefficient for the hoodless model is between 0,80-0,85.

Fixed Cone valves can be manufactured in sizes up to DN2000 and pressures up to 25bar. A wide range of construction materials is applicable such as different carbon steels and stainless steels. If containment of the jet is desired, a hood can be installed which concentrates the flow, for this type refer to H|412 model.
