When ordering, please allow up to 7 working days for delivery of this item.

Stainless steel expansion vessel for potable water applications.

Reliance Valves Aquasystem Replaceable Membrane Potable Water Expansion Vessels are designed to carry the extra load within a water system when the water is heating and increasing in volume. These expansion vessels ensure safe operating levels by preventing pressure from building up in sealed heating systems and cold water systems.

The vessels have a replaceable membrane inside that prevents the water from causing corrosion or contamination, ensuring the water remains safe for human consumption. This replaceable membrane also means that the vessel can be easily serviced without having to be removed to allow quick and easy servicing in situ.

Features and benefits:

- Stainless steel bolted flange prevents corrosion
- Extra wide membrane opening prevents noise caused by restricted flow
- Internal membrane prevents any water contact with the steel shell, stopping internal corrosion
- A wide range available from 2 to 5000 litres, covering all applications
- All versions supplied with a replaceable membrane so that the vessel can be serviced without being removed
- Pre-charge valve for topping up air pressure
- Suitable for hot and cold water only
