**PREL104013 High Capacity Potable Water Pressure Relief Valve** The PREL104013 High Capacity Potable Water Pressure Relief Valve is engineered to release water from the system at a predetermined pressure, effectively managing cold water over-pressurisation in unvented cylinders. Designed for high flow rates, this valve is particularly suitable for larger capacity systems. The Reliance Valves 104 Series provides reliable protection for unvented systems against over-pressurisation. Each valve is pre-set and securely locked to a specific pressure—if the system pressure surpasses this limit, the valve will lift from the seat, allowing water to discharge safely to waste. The valve's outlet connection is sized one inch larger than the inlet, ensuring optimal flow capacity during high discharge demands. As the primary safety device in an unvented system, these valves offer peace of mind and robust performance. Available in various pressure settings from 3.5 to 8 bar, and with multiple connection sizes for ease of installation, the PREL104013 is a versatile solution for any plumbing system. **Features and Benefits:** - **High Flow Design**: Ideal for larger capacity systems. - **Easy Maintenance**: Quick removal of the single-piece cartridge for cleaning or replacement. - **Durable Diaphragm**: Enhanced resistance against scale build-up ensures longevity. - **Over-Pressure Protection**: Guards against potentially damaging over-pressurisation. - **Flexible Installation**: Multiple connection options cater to diverse installation requirements. - **Adjustable Pressure Range**: Set relief pressure from 3.5 to 8.0 bar. - **Cold Water Usage**: Specifically designed for use with cold water. **Specifications:** - **Size**: 1.1/4" x 1.1/2" - **Connections**: BSP Female Inlet x BSP Female Outlet - **Materials**: Hot pressed DZR Brass - **Medium**: Cold Water - **Set Pressure**: 8 Barg - **Temperature Rating**: +140 degrees Celsius - **Product Code**: PREL104013 Ensure your unvented system is protected with the reliable performance of the PREL104013 High Capacity Potable Water Pressure Relief Valve. Perfect for both residential and commercial applications, this valve is essential for maintaining a safe and efficient plumbing system.
