Waterman Model AA-60D is designed to furnish the reliable pipeline protection you expect from all of our AA series pressure relief valves, while providing capture of the excess flow from discharge. This feature eliminates unwanted discharge moisture at the valve site by the addition of an aluminum hood installed with a threaded outlet port equal in diameter to the valve size. This allows the "piping off" of the discharge to a location where it is not a problem. The base, cover and spring retainer are corrosion resistant cast aluminum, while the spring shaft is stainless steel for long life. The AA-60D may be furnished with discharge pressure factory preset or equipped for field setting. Pressure settings for the AA-60D are available from 11 to 120 PSI. Aluminum hood also available in stainless steel and PVC.
