Singer Valve 106/206-DW Deep Well Pump Control Valve – Double Chamber - Product Guide

The 106-DW and 206-DW deep well pump control valves are installed in a tee between the pump discharge and the check valve. The valve is normally open, and, on pump start-up, a pilot solenoid is energized to start closing the valve at a rate governed by the closing speed control. Initially, the valve discharges air, water and sand to waste. The open valve discharges all pump flow. As the valve closes slowly, flow is transferred to the main line smoothly, increasing the pipeline flow without surges. When the valve is fully closed, all pump flow is in the pipeline, with no control valve losses.
