Design: Notes:

Enhance the reliability and efficiency of your refrigeration system today with our high-quality refrigeration check valves. Perfect for a variety of applications, these valves are designed to ensure optimal performance and longevity.

The Reliance Valves Aquasystem Stainless Steel Expansion Vessel is specifically designed for heating applications. Available in capacities ranging from 2 litres to 5000 litres and with maximum pressure ratings between 8.0 and 10.0 bar, these vessels feature replaceable membranes. The Aquasystem range allows for servicing on-site, ensuring that water does not come into contact with the steel expansion vessel shell, which helps to prevent internal corrosion and extend the vessel's lifespan.

Features and Benefits:

• Durable stainless steel bolted flange that prevents corrosion.
• Extra-wide membrane opening to minimise noise caused by restricted flow.
• Internal membrane design eliminates water contact with the steel shell, thus preventing internal corrosion.
• A comprehensive range from 2 to 5000 litres suitable for various applications.
• All models come with replaceable membranes for convenient servicing without removal.
• Pre-charge valve included for easy topping up of air pressure.
• Designed exclusively for heating applications.
