Abstract
A hydraulic valve device includes a first inlet port () and a second inlet port () and a valve element () for selectively closing one of the first and the second inlet port. The valve element (') is rotatable between two valve positions such that a surface of the valve element is moved in a direction parallel to openings of the inlet ports. The valve element includes two separate sealing portions (), a first sealing portion () for closing the first inlet port and a second sealing portion () for closing the second inlet port. The two sealing portions are arranged such that in a first valve position a first sealing portion closes the first inlet port and in a second valve position a second sealing portion closes the second inlet port. A centrifugal pump device includes such hydraulic valve device.
