Introducing the Reliance Valves Aquasystem Stainless Steel Expansion Vessel, expertly designed for potable water applications. These replaceable membrane expansion vessels are essential for managing the additional load within water systems as water heats up and its volume expands. By effectively regulating pressure in both sealed heating systems and cold water systems, these vessels ensure safe operational levels and prevent dangerous pressure build-up. Featuring a replaceable membrane, the design prevents water from coming into contact with the steel shell, thereby eliminating issues of corrosion and contamination and keeping the water safe for human consumption. This innovative feature also allows for swift and efficient servicing in situ, so there's no need to remove the vessel for maintenance.
