**Stainless Steel Expansion Vessel for Potable Water Applications** The Reliance Valves Aquasystem Replaceable Membrane Potable Water Expansion Vessels are expertly designed to accommodate the increased load within a water system as water heats and expands. These expansion vessels play a crucial role in maintaining safe operating levels by effectively preventing pressure build-up in both sealed heating systems and cold water systems. Featuring a replaceable membrane, these vessels prevent water from coming into contact with the steel shell, thereby avoiding corrosion and contamination, ensuring that the water remains safe for human consumption. The replaceable membrane also allows for easy servicing without the need to remove the vessel, enabling quick and efficient in-situ maintenance. **Features and Benefits:** - **Corrosion-Resistant Design:** The stainless steel bolted flange prevents corrosion, ensuring durability and longevity. - **Quiet Operation:** The extra-wide membrane opening helps reduce noise resulting from restricted flow. - **Protective Internal Membrane:** Prevents any direct contact between water and the steel shell to stop internal corrosion. - **Versatile Capacity Range:** Available in sizes from 2 to 5000 litres, suitable for a variety of applications. - **Easy Servicing:** All models come equipped with a replaceable membrane, allowing for servicing without vessel removal. - **Pre-Charge Valve:** Convenient for topping up air pressure. - **Hot and Cold Water Compatibility:** Designed specifically for hot and cold water use only. **Specifications:** - **Capacity:** 24 Litres - **Colour:** White - **Pre-Set Pressure (Bar):** 3 - **Max Pressure (Bar):** 10.0 - **Minimum Temperature:** -10°C - **Maximum Temperature:** 99°C - **Height:** 489mm - **Diameter:** 280mm - **Water Connection:** 3/4" MBSP - **Miscellaneous:** Comes complete with wall bracket and accessories - **Product Code:** XVES050065 **Materials:** - **Shell:** Epoxy Coated Steel - **Membrane:** EPDM - **Bolted Flange:** Stainless Steel **Standards and Approvals:** - WRAS approved for tanks up to 1000 litres - CE marked in accordance with Directive PED 97/23/CE - TÜV Certified - Materials for 1000 - 5000 litre models comply with BS 6920 Enhance your potable water system with the Reliance Valves Aquasystem Expansion Vessel, designed for efficiency, safety, and ease of maintenance.

The AURA EXZ is a sub-atmospheric back-pressure regulator specifically designed to provide adjustable relief for excess positive pressure in vacuum systems, which can occur due to pressure build-up or upstream sample injection. Featuring a proprietary hybrid spring system and an oversized dual-surface diaphragm, the AURA EXZ guarantees exceptional precision, stability, and repeatability in its performance. With multiple seat material options available, this regulator effectively eliminates any unwanted reactions with process media, allowing for accurate throttling of excess pressure and helping to maintain optimal process conditions. Each AURA EXZ regulator is meticulously assembled in a Class 100 cleanroom, complete with all necessary gauges, fittings, and valves. The assembly undergoes thorough cleaning for oxygen service, is 100% helium leak tested, and is subjected to comprehensive flow and function tests to ensure long-term reliability, durability, and leak integrity, even in the most demanding environments worldwide. For applications that involve highly corrosive or aggressive substances, the AURA EXZ can be equipped with Dursan® LS inert coating technology, providing superior resistance to acidic and caustic media compared to traditional exotic alloys. This inert surface not only prevents moisture and media absorption but also ensures consistent performance in sensitive processes. With its precision control, advanced material options, and robust construction, the AURA EXZ is the ideal choice for accurate and reliable excess pressure control in sub-atmospheric applications.
