Air injection is an effective way to reduce or prevent the damaging effects of a water hammer caused by transient vacuums. This article will discuss why and where vacuums can form, and how to size air injection valves to prevent problems.

The problem with this type of valve is that they only lasted a few months because they were not used only as full open-or-closed isolation valves. Besides being used to isolate the centrifugal pumps for maintenance, the valves were also used on the discharge of the pumps to assist the pump during startup to develop head pressure. That required them to be placed in the near closed position. Unfortunately, the velocity of the acid that was developed while nearly closed was so high that it physically removed the thin PVDF coating covering and protecting the ductile iron disc. This exposed the iron disc and the acid simply dissolved it. Of note, the originally supplied titanium valves are still in service 22 years later. Sometimes buying cheap costs more in the longterm.
