Bi-level control valve (Differential Float valve) HYDRAULIC VALVES Description Hydraulic control valve used to control water level in tanks and reservoirs by means of a differential float valve. When the water reaches the upper preset level the valve closes completely and doesn’t open until the water reaches the lower selected level. This system avoids the frequent starts and stops of the pump getting so to decrease the pumping costs and extending the life of the pump. Applications This valve is used to control the maximum and minimum level of water in tanks and reservoirs.
