Stainless Steel Expansion Vessel for Potable Water Applications

The Reliance Valves Aquasystem Replaceable Membrane Potable Water Expansion Vessels are expertly designed to accommodate the increased load within water systems as water is heated and expands. These expansion vessels play a crucial role in maintaining safe operating levels, preventing excessive pressure build-up in both sealed heating and cold water systems. Each vessel features a replaceable membrane that safeguards against corrosion and contamination, ensuring that the water remains safe for human consumption. The inclusion of a replaceable membrane also facilitates easy servicing of the vessel without requiring removal, allowing for quick maintenance in situ.

Features and Benefits:
