**Stainless Steel Expansion Vessel for Potable Water Applications** The Reliance Valves Aquasystem Replaceable Membrane Potable Water Expansion Vessels are expertly designed to manage the additional load within a water system when the water is heated and expands. These expansion vessels play a crucial role in maintaining safe operating pressures, effectively preventing the build-up of pressure in both sealed heating systems and cold water systems. Featuring a replaceable membrane, these vessels ensure that the water does not come into contact with the steel shell, thereby avoiding corrosion and contamination, and guaranteeing that the water remains safe for human consumption. The innovative design allows for easy servicing of the vessel without the need for removal, facilitating quick and convenient maintenance in situ. **Features and Benefits:** - **Corrosion-Resistant Design:** The stainless steel bolted flange prevents corrosion, ensuring longevity. - **Enhanced Flow:** Extra wide membrane opening mitigates noise associated with restricted water flow. - **Safe Water Storage:** The internal membrane isolates the water from the steel shell, preventing internal corrosion. - **Diverse Capacity Options:** Available in a wide range from 2 to 5000 litres, accommodating all applications. - **User-Friendly Maintenance:** All models are equipped with a replaceable membrane, allowing for servicing without removal. - **Pressure Regulation:** Comes with a pre-charge valve for easy air pressure adjustments. - **Hot and Cold Water Compatibility:** Suitable for use with both hot and cold water systems. **Specifications:** - **Capacity:** 8 Litres - **Colour:** White - **Pre-Set Pressure (Bar):** 3.5 - **Maximum Pressure (Bar):** 10.0 - **Minimum Temperature:** -10°C - **Maximum Temperature:** 99°C - **Height:** 316 mm - **Diameter:** 200 mm - **Water Connection:** 3/4" MBSP - **Product Code:** XVES050036 **Materials:** - **Shell:** Epoxy Coated Steel - **Membrane:** EPDM - **Bolted Flange:** Stainless Steel **Standards and Approvals:** - WRAS approved for models up to 1000 litres - CE marked in accordance with Directive PED 97/23/EC - TÜV Certified - Materials for 1000 to 5000 litre models comply with BS 6920 Ensure the safety and efficiency of your water systems with the Reliance Valves Aquasystem Replaceable Membrane Potable Water Expansion Vessels. Ideal for both domestic and commercial applications, these vessels are your reliable solution for managing water pressure and 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.
