The D-43 series Combination Air Valve has the features of both an air release valve and an air & vacuum valve. The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure. The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs. Applications Pump stations: after the pump and after the check valve. Downstream (after) and upstream (before) of shut-off valves. After deep-well pumps. On long constant-sloped pipeline segments. At peaks along the pipeline and at peaks relative to hydraulic gradient. At end lines.
