Air Release Valve Sizing

From the smallest simple lever air release valve to the largest surge suppression combination air valve all are provided standard with type 316 stainless steel trim and floats.

Air release valve sizing.

All val matic air valve floats are unconditionally guaranteed. The valve has a small precision orifice in the range of 0 0625 in 1 6 mm to 0 5 in 13 mm to release air under pressure continuously during pipeline operation. We supply a numerous amount of different valves and variation of valves dependent on our customers needs. An air release valve has a small precision orifice in the range of 0 0625 in 1 6 mm to 0 5 in 13 mm and has a float and linkage mechanism which triggers the opening of the orifice upon sensing the air.

Air release valves potable water. Because of this the valves can exhaust large volumes of air. Reduction of damage and hindrance to wastewater transmission systems caused by air pockets by deployment of air valves. Air release valves are probably the best known air valve and are typically furnished in sizes 0 5 in 13 mm through 3 in 76 mm.

For many decades sizing orifices for air release valves has been a mystery. An air release valve can open against internal pressure because the internal lever mechanism multiplies the float force to be greater than the internal pressure. Recent research studies and surveys have shown that air pockets in wastewater transmission systems cause extensive damage and hindrance. Air entrapped in pipelines is an invisible culprit and no quantitative means exist to determine the precise amount of entrapped air in a flooded transmission pipeline.

Among these are our pressure air release valves air vacuum valves and combination valves. Web based air valve sizing software the web based val matic air valve program enables you to enter design information specific to your pump water pipeline or wastewater forcemain and calculate the locations and sizes of awwa air valves. Air release valves or air relief valve function to release air pockets that collect at each high point of a full pressured pipeline. Crispin s air release valves potable water are nsf 61 and 372 certified.
