Hemiwedge Valve Corporation was formed to develop and commercialize a new patented technology addressing significant needs in the global valve market. The Hemiwedge cartridge valve is a quarter-turn hemispherical wedge valve, engineered to provide substantial performance improvements over existing products in the marketplace today, such as traditional ball, gate and butterfly valve designs.\r\n The patented design of the Hemiwedge cartridge valve combines the benefits of quarter turn valves with the durability of gate valves. The Hemiwedge cartridge valve has a non-rotating core which guides the fluid flow through the valve to the Hemiwedge itself. The hollow hemisphere's inner and outer walls are slightly offset with non-concentric centers, providing a hemispherical wedge shape - the Hemiwedge. Operation of the valve rotates the Hemiwedge a quarter turn and moves it between the core and valve seat, thus controlling the flow. The design features in the combination of the Hemiwedge shut off and stationary core make the Hemiwedge cartridge valve the most innovative valve design in the industry today.\r\n
