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.

Features and Benefits:

• Durable stainless steel bolted flange to prevent corrosion
• Extra-wide membrane opening to minimise noise caused by restricted flow
• Internal membrane ensures no water contacts the steel shell, preventing internal corrosion
• A comprehensive range available from 2 to 5000 litres, suitable for all applications
• All models come with a replaceable membrane for easy servicing without removal
• Equipped with a pre-charge valve for convenient air pressure adjustments
• Designed exclusively for hot and cold water usage
