Reliance Water Controls (RWC) Expansion Vessels

Reliance Valves Expansion Vessels ensure safe operating levels by preventing pressure from building up in sealed heating systems and cold water systems.

Their Aquasystem range features replaceable membranes to allow quick and easy servicing in situ. It also prevents water from coming into contact with the shell, eliminating corrosion and extending product lifespan.

Available with 2 to 5,000 litre capacity, RWC expansion vessels are suitable for both domestic and commercial applications. The range also includes replacement membranes and expansion vessel fixing kits for fast and simple installation.
