The primary purpose of a pressure or vacuum relief valve is to protect life and property by venting process fluid from an over pressurized vessel or adding fluid (such as air) to prevent formation of a vacuum strong enough to cause a storage tank to collapse. Proper sizing, selection, manufacture, assembly, testing, installation, and maintenance of a pressure relief valve are all critical for optimal protection of the vessel or system.

We use 2'' #825YA Angle Reduced Pressure Assembly (RPA) in the sprinkler systems that we install. Our irrigation technicians at S&E Ward's spec out the #825YA Angle Reduced Pressure Assembly (RPA) when it is appropriate in order to provide the best performance possible of our irrigation systems.
