A valve for switching over liquid paths, particularly for pressure exchanger installations with tubular pressure exchanger chambers () through which an alternating flow occurs, in which a rotatable control element () having a plurality of flow paths is mounted in a housing (), which in turn comprises a plurality of connection opening () connected to a first pipe system and to an end of at least one pressure exchanger. Another end of the pressure exchanger is connected to a second pipe system through a valve. A motorized drive shaft () rotates the control element so as to alternately connect the control element flow paths to openings inside housing (). Oncoming flow to the control element may come from an axial direction or from a radial direction, and outgoing flow from the control element occurs in the axial direction.

Valve unit for pressure exchanger installations

A valve for switching fluid paths, particularly for pressure exchanger installations with tubular chambers through which fluid flows in an alternating manner, including a rotatable closing element () provided with a motorized drive shaft () and arranged inside a housing () having a plurality of connections () for connecting lines leading to a pipe system and to a respective end of at least one pressure exchanger. Another end of each pressure exchanger is connected through a valve arrangement to a second pipe system. A splitter () provided with a plurality of overflow paths () is arranged inside the housing (); mouths of the overflow paths are located on two axial end faces () and on the circumference of the splitter (), and a rotatable, disk-shaped control element () is arranged in a sealing manner at each end face of the splitter ().
