Introducing our stainless steel expansion vessel, specifically engineered for potable water applications. The Reliance Valves Aquasystem Replaceable Membrane Potable Water Expansion Vessels are ideal for managing the increased water volume as it heats, effectively absorbing the extra load within your water system. These vessels are essential for maintaining safe operating levels, as they effectively prevent pressure build-up in both sealed heating and cold water systems. At the heart of our expansion vessels is a replaceable membrane, expertly designed to protect against corrosion and contamination, ensuring that the water remains safe for human consumption. The clever design also allows for easy servicing of the vessel without removal, providing a simple solution for maintenance in situ. **Key Features and Benefits:** - **Corrosion Resistance:** The stainless steel bolted flange ensures durability and prevents corrosion. - **Noise Reduction:** The extra-wide membrane opening mitigates noise caused by restricted flow. - **Protective Membrane:** An internal membrane prevents any water contact with the steel shell, effectively halting internal corrosion. - **Versatile Capacity Range:** Available in sizes from 2 to 5000 litres to accommodate all applications. - **Serviceable Design:** All versions come equipped with a replaceable membrane, allowing for efficient servicing without the need to remove the vessel. - **Pre-charge Valve:** Included for easy topping up of air pressure. - **Temperature Compatibility:** Suitable for use with both hot and cold water. **Specifications:** - **Capacity:** 35 Litres - **Colour:** White - **Pre-Set Pressure (Bar):** 3 - **Maximum Pressure (Bar):** 10.0 - **Minimum Temperature:** -10°C - **Maximum Temperature:** 99°C - **Height:** 440mm - **Diameter:** 365mm - **Water Connection:** 3/4" MBSP - **Miscellaneous:** Comes complete with wall bracket accessories - **Product Code:** XVES050075 **Materials:** - **Shell:** Epoxy Coated - **Membrane:** EPDM - **Bolted Flange:** Stainless Steel **Standards and Approvals:** - **WRAS approved** for capacities up to 1000 litres - **CE marked** according to Directive PED 97/23/CE - **TUV Certified** - **Compliant with BS 6920** for 1000 - 5000 litre models Ensure the integrity and safety of your potable water systems with our premium stainless steel expansion vessels.
