Diaphragm-actuated, Rigid Seal, Y-pattern, 3-way, Differential Float Level Control Valve

DOROT S500 FLDI (3W), is a Diaphragm-actuated, Rigid Seal, Y-pattern, 3-way, Differential Float Level Control Valve. This automatic, pilot-controlled, level-control valve is activated by the pressure of the pipeline. The valve closes when the water rises to a set maximum level and opens when the water level drops to a preset minimum point. The differential between opening and closing levels is adjustable.
