Reliance RWC Anti-Legionella Valve

**PREL104010 High Capacity Potable Water Pressure Relief Valve** The PREL104010 High Capacity Potable Water Pressure Relief Valve efficiently discharges water from the system at a predetermined pressure, safeguarding against the over pressurisation of cold water in unvented cylinders. Specifically designed for larger capacity systems, the Reliance Valves 104 Series provides robust protection for unvented systems, ensuring they remain operational and safe. These high-capacity pressure relief valves are pre-set and locked to a specific pressure. When system pressure exceeds this threshold, the valve activates by lifting off its seat, allowing water to discharge safely to waste. The outlet connection is sized larger than the inlet, guaranteeing that the valve can handle high-capacity discharges without issue. As a critical safety component in unvented systems, our valves come in various pressure settings from 3.5 to 8 bar and feature multiple connection sizes to accommodate flexible installation options. **Features and Benefits:** - **High Flow Design:** Tailored for larger capacity systems to ensure efficient operation. - **Easy Maintenance:** Rapid removal of the single-piece cartridge simplifies cleaning or replacement. - **Enhanced Durability:** The diaphragm design improves resistance to scale build-up, promoting longevity. - **Safety Assurance:** Provides reliable protection against over pressurisation in your system. - **Versatile Installation:** Multiple connection sizes ensure flexibility during installation. - **Variable Set Pressure:** Relief pressure settings range from 3.5 to 8.0 bar for varied system requirements. - **Cold Water Use:** Specifically designed for cold water applications only. **Specifications:** - **Size:** 3/4" x 1" - **Connections:** BSP Female Inlet x BSP Female Outlet - **Materials:** Hot Pressed DZR Brass - **Medium:** Cold Water - **Set Pressure:** 6 Barg - **Temperature Rating:** +140°C - **Product Code:** PREL104010 Ensure the safety and efficiency of your unvented water systems with the PREL104010 High Capacity Potable Water Pressure Relief Valve – the ideal choice for superior performance and reliability.

The AURA EXF is meticulously designed for the primary control of high-flow gases and liquids, operating efficiently at delivery pressures of up to 250 psig. Its balanced stem seat design accommodates larger orifices and seat sizes to facilitate higher flow rates, all while eliminating the necessity for spring-assisted shutoff. This innovative design minimises outlet pressure fluctuations, ensuring stable and reliable performance. The EXF features AURA’s advanced dual-surface diaphragm, which provides precise and sensitive pressure control, even at low pressure levels. With a 0.8 orifice size and ½” process ports, the EXF guarantees optimal flow capacity for demanding applications. Utilising a precision machining process, AURA achieves ultra-smooth surface finishes of 4–25 Ra, significantly reducing corrosion and extending the service life of the regulator. Its minimal internal volume also lowers purge gas requirements, thereby enhancing overall system efficiency. Each EXF regulator is assembled in a Class 100 cleanroom as a complete unit, with all gauges, valves, and fittings pre-installed. The assembly undergoes thorough cleaning for oxygen service, is 100% helium leak tested, and is subjected to multiple flow and function tests to ensure purity, durability, and leak integrity in even the most challenging environments. For applications that are highly acidic or caustic, the EXF is available with Dursan® LS inert coating technology, offering exceptional corrosion resistance in comparison to exotic alloys or passivated surfaces. By merging its balanced stem seat design with advanced material options, the AURA EXF provides the performance, flexibility, and reliability that engineers trust for high-flow applications worldwide.
