The BTL foot valve, Model H42X-10, is a specialized check valve installed at the end of the suction pipe in water pumping systems. This device performs two core tasks. First, it acts as a check valve, holding the water column in the pipeline when the pump stops, so the pump does not lose its prime. Second, its strainer section keeps large debris and sediment from entering and jamming or damaging the valve disc and the pump impeller.<\/p>\n
