Kunkle Valve industrial and commercial safety and relief valves are made for steam, air, gas, liquid, cryogenic, and nonhazardous gas applications. Products are available for ASME Section I, Section IV, and Section VIII applications, with relief capacities certified by the National Board of Boiler and Pressure Vessel Inspectors. Code and non-code versions are set, tested, and certified to customer specifications and sealed according to ASME specifications.
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.
