**PREL102005 Reliance Water Controls (RWC) 102 Series Potable Water Pressure Relief Valve** The PREL102005 Reliance Water Controls (RWC) 102 Series Potable Water Pressure Relief Valve is designed to efficiently discharge water from the system at a predetermined pressure, safeguarding against cold water over-pressurisation in unvented cylinders. This essential safety device is engineered to protect unvented systems by preventing over-pressurisation. The valves are pre-set and secured to a specific pressure; should the system exceed this limit, the valve will lift from its seat, allowing water to discharge safely into the waste system. Crafted with a single-piece cartridge, the Reliance Valves 102 Series provides a variety of pressure settings, ranging from 3.5 to 8 bar, and offers multiple connection sizes for versatile installation options. **Features and Benefits:** - Quick and easy removal of the single-piece cartridge for maintenance or replacement - Innovative diaphragm design enhances resistance to scale build-up - Reliable protection against over-pressurisation - Versatile connections allow for flexible installation - Adjustable relief pressure range from 3.5 to 8 bar - Suitable exclusively for cold water applications **Specification:** - Size: 1/2" x 15mm - Connections: BSP Male Inlet x Compression Outlet - Materials: Hot-pressed DZR Brass - Medium: Cold water - Set Pressure: 6 Barg - Temperature: +140°C - Product Code: PREL102005 Upgrade your unvented system's safety with the PREL102005 Reliance Water Controls 102 Series Potable Water Pressure Relief Valve—ensuring peace of mind and compliance with UK safety standards.

The Medenus RS251 Gas Pressure Regulator and Shut Off Valve guarantees a stable outlet pressure independent of the primary inlet pressure. It effectively accommodates variations in gas usage and provides rapid pressure regulation when the flow rate experiences sudden changes. The integrated safety shut off valve guarantees secure operation by shutting off the gas flow if the pressure exceeds or drops below safe levels.

Designed to meet the DVGW Code of Practice G260/262, the Medenus RS251 Gas Pressure Regulator and Shut Off Valve is compatible with all neutral and non-corrosive gases (other gases available upon request). This versatile regulator is offered with flange connections ranging from DN25 to DN200 and operates effectively at working pressures of up to 8 bar. All Medenus gas pressure regulators are certified by DVGW and CE, ensuring compliance with the highest safety standards.

The RS-series regulators come with a variety of options, including a safety membrane, vent valve, remote release of SSV, noise reduction features, and more. For additional information, please consult our documentation or contact us directly.
