Introducing the Reliance Valves Aquasystem Stainless Steel Expansion Vessel, expertly designed for potable water applications. These replaceable membrane expansion vessels are essential for managing excess pressure in water systems as the water heats up and expands. By preventing pressure build-up in both sealed heating systems and cold water systems, these vessels ensure safe operational levels. The internal replaceable membrane safeguards against corrosion and contamination, thereby guaranteeing that the water remains safe for human consumption. Moreover, the design allows for quick and efficient servicing without the need to remove the vessel from its installation.
