Air Valves
air valves are integral part of long water transmission mains and are essential for removal of bulk and residual air during initial and subsequent filling operations. Air valves are also becoming...
Air valves are an important tool for surge dampening and suppression. Accurate air valve specification, location and sizing are vitally essential for effective, efficient liquid flow and for...
Water column separation events occur at sudden water supply-demand differentials when the flow rate downstream from the point of separation is much higher than the flow rate upstream from this...
This paper deals with analysis of energy losses related to large undissolved air pockets in pipelines for water transportation.
Houston typically uses 4” conventional slow closing combination air valvesair release valves on the water wells that provide most of the water used by Houston. This design was selected to attempt to...
