PA Bottom Blowdown Globe valves are intermittent valves for the manual removing of boiler sludge from land or marine installations. They are particularly designed for installations operated without constant supervision in accordance with TRD 604. Sludge sediments, which are accumulated precipitates from boiler water that settle at the bottom of the boiler, are removed from the steam boiler with the the aid of valve MPA. These valves give the boiler a short blow at regular intervals, thereby discharging accumulated sludge and sediments.
