Abstract
Valve with multi-piece stator assembly for use with liquid chromatography or other analytical systems. A separate and removable stator plate is provided with a mounting device to provide a multi-piece stator assembly. The mounting device is adapted on one side to engage and contact the stator plate, and on the other side includes a plurality of ports for fluidic connections which are in fluid communication with fluid passageways in the stator plate. By making the stator face a separate component, the overall costs of the valve can be reduced, different materials can be used for the mounting device and the stator, and the valve can be used for ultra-high pressure applications, including in liquid chromatography and other analytical instrument systems.
