Gathered air bubbles cause the float to drop, opening the valve and forcing the air out under water pressure until the float rises and once again seals the valve.  \nApplication  \nThe Auto Air Vent is an air and vacuum relief valve designed for use with solar and recirculated hot water systems.  \nRefer to solar hot water system manufacturers’ installation requirements for the correct positioning of the valve in the system . Typically, the valve is installed at the highest point of the solar hot water system, or at a location where air bubbles are likely to accumulate.  \nIf installed in a recirculated hot water system, the valve will need tobe positioned over a tundish.  \n[rmc.com.au](rmc.com.au | 1800 810 803 | sales.au@rwc.com)[ |](rmc.com.au | 1800 810 803 | sales.au@rwc.com)[ 1800 810 803](rmc.com.au | 1800 810 803 | sales.au@rwc.com)[ |](rmc.com.au | 1800 810 803 | sales.au@rwc.com)[ sales.au@rwc.com](rmc.com.au | 1800 810 803 | sales.au@rwc.com)  \n| Features and Benefits |  |\n| --- | --- |\n| • Convenient connection size which removes the need for adapters and additional joins in pipe work\u003Cbr>• Stainless steel float\u003Cbr>• Capable of withstanding high pressures when commissioning solar hot water systems\u003Cbr>• ‘Always open’ vent cap\u003Cbr>• Valve will still vent air with the cap fully screwed down which avoids potential installation issues\u003Cbr>• Vent cap designed to minimize the risk of blockage due to foreign matter\u003Cbr>• Dezincification resistant\u003Cbr>• Chrome plated brass body meets Australian Standard for potable water supply\u003Cbr>• High temperature Viton® O-Rings\u003Cbr>• Individually tested |  |\n| Materials |  |\n| Body | Chrome plated DR brass |\n\nFloat  \nStainless steel  \n\n| Internal components | Stainless steel |\n| --- | --- |\n| Seals | Viton® high temperature |\n| Cap/stem/cover/locating screw | Chrome plated DR brass |\n\nExternal retaining ring/locknut Chrome plated brass  \n(non-wetted parts)  \nValves and Plumbing  \nAuto  \nAir Vent  \n\n| Working Pressuresand Temperatures |  |\n| --- | --- |\n| Maximum temperature | 230°C |\n| Maximum working pressure | 1400kPa |\n\nConnection  \nR½ BPST  \nNote  \nThe Auto Air Vent valve must be installed in its vertical orientation.
