**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 Berluto DRV578SW Seawater Reducing Valve has been expertly designed for applications involving seawater, making it ideal for use on ships, oil rigs, and in desalination facilities.
