Pratt introduces the brand new AirPro Max air valve line. Our comprehensive air valve line features all ductile iron bodies and covers as well as 316 stainless steel floats and trim as standard. Pratt valves represent a long-term commitment to both the customer and to a tradition of product excellence. This commitment is evident in the number of innovations we have brought to the industries we serve. In fact, the Henry Pratt Company was the first to introduce many of the flow control products in use today, including the first rubber seated butterfly valve, one of the first nuclear N-Stamp valves, and the bonded seat butterfly valve.

AirPro Max™ Series WAR Air Release Valves are designed to vent trapped air that collects at high points in a pipeline. These valves continuously release air from systems thereby preventing large air pockets to form which can cause damaging pressure surge to the system. In many installations lacking Air Release Valves, large pockets of air in the pipeline will cause power consumption to increase, and flow to decrease, possibly completely. Another possible result of excessive air accumulation is the inexplicable pipeline rupture that is mistakenly attributed to ground settling or defective pipe. In reality unusually large air pockets can greatly increase the pressure of normally occurring surges to the point where sudden stops and starts of flow can cause a pipe to rupture.

As air accumulates in the air valve, water is displaced, causing the stainless steel float to drop to a point where the valve orifice opens and the accumulated air is exhausted into the atmosphere. The water level in the air valve then rises and closes the valve orifice once again. This cycle repeats as needed and avoids the formation of potentially destructive air pockets.
