BPG 7829 Solar Set
Properties
BPG 7829 Solar Set combines next-generation engineered components in an innovative design built to withstand the extreme conditions of molten salt applications. A protective metal cap at the bottom shields against aggressive or oxidizing media, while a top cap protects against atmospheric effects at high temperatures. At its core, an advanced sealing composition with progressive low-friction impregnation ensures superior resistance to aggressive media. Supported by intermediate mineral-based high-temperature barrier discs, the set delivers a reliable, low-leakage sealing solution for critical solar and high-temperature applications.
Applications
BPG 7829 has been especially developed as a sealing element for high temperature and corrosive resistant valves used in molten salt applications. These high temperature valves are currently in use at Concentrating Solar Plants (CSP) where molten salts are being used as a substitute to conventional heat transfer fluids, such as heat transfer oils and steam.
