Abstract
A sliding valve having a flow line on which there may be placed a module having flow channel that can be connected and disconnected. The valve avoids the problem of liquid remaining in the flow channel of a first valve component by providing flow channel intersecting segment which intersects both components of the sliding valve so that in a module disconnecting orientation, each valve component defines separate segments of the flow channel while in the connected orientation, the valve components define a single flow channel. The construction allows for liquid flow through the valve independent of the module being in connected or disconnected position.
