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 WAV Air Vacuum Valves are high capacity air venting and intake valves designed to provide two separate functions. First, as the line is being filled with water they allow large quantities of air to be vented from the pipeline. When air has been completely vented, water enters the valve causing the stainless steel float to rise and seal tightly against the seat to prevent leakage. Second, when the line is drained, either intentionally or as a result of power failure or pipeline breakage, the air vacuum valve responds to a negative pressure and opens, allowing air to re-enter the valve and line preventing a vacuum from forming which could lead to damaging the pipeline.

Series WAV Air Vacuum Valves do not open when closed and pressurized to exhaust any air that collects at high points during operation of the system. Series WAR Air Release Valves are needed for this function.

Series WAV Air Vacuum valves can be fitted with internal diffusers and/or throttling devices for well service applications. Internal diffusers and throttling devices are available for valves sized ½” – 3”. Please specify these options when ordering.
