These high-quality stainless steel expansion vessels play a crucial role in maintaining safe operating levels by preventing pressure build-up in both sealed heating systems and cold water systems. Featuring a replaceable membrane, our vessels effectively prevent corrosion and contamination, ensuring the water remains safe for human consumption. This innovative design allows for quick and easy servicing in situ, eliminating the need to remove the vessel entirely. **Key Features and Benefits:** - **Corrosion-Resistant Design:** The stainless steel bolted flange helps to prevent corrosion. - **Enhanced Flow:** Extra wide membrane opening substantially reduces noise caused by restricted flow. - **Internal Protection:** The internal membrane prevents any contact between water and the steel shell, effectively stopping internal corrosion. - **Extensive Range:** Available in capacities from 2 to 5000 litres, catering to a variety of applications. - **Serviceable Design:** All models come equipped with a replaceable membrane for straightforward servicing without removal. - **User-Friendly:** Pre-charge valve for easy topping up of air pressure. - **Versatile Compatibility:** Suitable for hot and cold water systems only. **Specifications:** - **Capacity:** 4000 Litre - **Colour:** Red - **Pre-Set Pressure (Bar):** 4 - **Max Pressure (Bar):** 10.0 - **Minimum Temperature:** -10°C - **Maximum Temperature:** 99°C - **Height:** 3200mm - **Diameter:** 1450mm - **Water Connection:** DN80 **Product Code:** XVES050210 **Materials:** - **Shell:** Epoxy Coated - **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/CE - TÜV Certified - Materials for 1000 - 5000 litre models comply with BS 6920 Choose the Reliance Valves Aquasystem Potable Water Expansion Vessel for a reliable and efficient solution to your water system needs!

NABIC 568 Anti-Vacuum Valves are essential for safeguarding drying cylinders, calorifiers, and tankers against collapse caused by internal vacuum conditions. These valves are equally valuable in steam systems, where they facilitate effective condensate drainage and prevent the unwanted suction of contents from vats. Typically, vacuum valves are installed vertically at the top of the vessel or pipeline they protect. In the case of horizontal revolving cylinders, a NABIC 568 valve should be fitted at each end, positioned directly opposite each other. Our NABIC Valves are backed by an industry-leading 5-Year Guarantee for your peace of mind.
