Abstract
The invention consists of a combination fluid-control-switch valve adapted for monitoring water flow in water-supply systems so as to enable a purification or treatment system therein to operate as the water is being used. The valve comprises a two-section housing, wherein an upper section thereof defines a sealed switch compartment having a switch that is actuated by the movement of a magnet mounted to a pivot arm, and a lower independent section defining a flow chamber having an inlet port and an outlet port, and wherein a poppet valve is located in the flow chamber defined by a slidable valve stem that includes a calibrated washer for setting the flow rate of the water passing through the chamber, a back-flow plate preventing the treated water from becoming contaminated when the system is not in use. Attached to the valve stem is a second magnet that moves up and down with the valve stem and thereby causes the movement of the arm mounted magnet to engage the switch in the switch compartment so as to turn the switch on and off as required.
