Description

GVK GER series eccentric ball valve is Designed with a rugged and well sized non-cross-over shaft, higher flow capacities can be achieved for every valve size. This superior quality design characteristic eliminates potential damage caused by corrosive and/or heavy slurry processes.

In most conventional rotary control valves the shaft crosses over the valve stream line therefore causing a significant reduction in flow capacity and additionally causing unnecessary wear of the shaft. The GVK ER series eccentric ball valve configuration assures a higher Cv capacity. While in the open position the streamlined fluid flow is not affected since the plug is kept totally retracted and away from the natural flow of the medium.

When the plug moves to the closed position, and due to its double-eccentricity configuration, the plug slides easily into its seat in such an angle that eliminates any direct metal-to-metal contact with its seat. This unique design characteristic contributes to drastic reductions of seat wear, therefore, less maintenance and service requirements.
