Introducing our stainless steel expansion vessel specifically designed for potable water applications. The Reliance Valves Aquasystem Replaceable Membrane Potable Water Expansion Vessels are essential for managing the additional load in water systems as the water heats and expands. These expansion vessels maintain safe operating levels by preventing the build-up of pressure in both sealed heating systems and cold water systems. Featuring a replaceable membrane, they effectively protect the water from corrosion and contamination, ensuring it remains safe for human consumption. This innovative membrane allows for hassle-free servicing without the need to remove the vessel, facilitating quick and efficient in-situ maintenance.

**Features and Benefits:**

• Robust stainless steel bolted flange to prevent corrosion
• Extra wide membrane opening reduces noise from restricted flow
