Air Valve Big is frequently installed at the highest point on a pipeline. This valve continuously removes undesired air throughout system operation. A reverse pressure is produced as a result of the buildup of air, obstructing the flow of water. As a result, this valve is placed at the pipe's summit to let the collected air out. Air Valve Big is used in order to prevent unintended surges and preserve system efficiency. This is very effective and economical to use.
