A piston () which includes a plurality of annular flow passages and a longitudinal flow passage is selectively movable within a bore () within the valve body through operation of a valve controller (). The valve controller is selectively operative to control the position of the piston so as to enable liquid flow through a plurality of flow paths. The valve controller further includes a installable and removable valve controller housing () which is releasably engageable with a valve base (). The valve may include a changeable piston and changeable injector and plug components to adapt the valve to different flow and fluid mixing requirements.
