The Reliance Water Controls (RWC) TPR15 Pressure & Temperature Relief Valves are compact devices engineered to safeguard against over-pressurisation within unvented hot water systems. These valves are essential when input temperature or pressure controls fail, preventing potential hazards. Specifically designed for installation at the upper section of a hot water cylinder—where the highest temperatures within the system occur—these valves ensure your system operates safely and efficiently. When temperatures exceed 95°C, the wax mixture in the temperature probe element expands, lifting the valve off its seat to release excess water, reducing pressure within the cylinder. In instances where water pressure increases without a corresponding temperature rise, the valve remains closed until the set pressure of the relief mechanism is attained, at which point it opens to relieve the excess pressure. Additionally, some models are equipped with a PTFE coating on the MBSP inlet thread, which significantly streamlines the installation process.

• Protects against temperatures exceeding 95°C

**PREL107020 Potable Water Pressure Relief Valve** The PREL107020 Potable Water Pressure Relief Valve is specifically engineered to safeguard unvented cylinders from cold water over-pressurisation. Part of the Reliance Valves 107 Series, this pressure relief valve effectively discharges water from the system when a designated pressure threshold is exceeded, ensuring optimal safety and performance. The valves come pre-set and securely locked to a specific pressure; should the system experience over-pressurisation, the valve will lift from its seat, allowing excess water to flow to waste. This valve acts as the primary safety device within any unvented system. Available in pressure settings ranging from 3.5 to 6 bar, the PREL107020 also features various connection sizes, providing flexibility for installation. **Features and Benefits:** - **Diaphragm Design:** Enhanced resistance to scale build-up. - **Over-Pressurisation Protection:** Ensures your system operates safely, preventing potential damage. - **Multiple Connection Options:** Allows for versatile installation to suit different setups. - **Set Relief Pressure Range:** 3.5 - 6.0 bar, accommodating various system requirements. - **Cold Water Use Only:** Specifically designed for cold water systems, ensuring efficiency and safety. **Specifications:** - **Size:** 1/2" x 15mm - **Connections:** BSP Male Inlet x Compression Outlet - **Materials:** Hot Pressed DZR Brass - **Medium:** Water - **Set Pressure:** 3.5 Barg - **Temperature Rating:** Up to +110°C - **Product Code:** PREL107020 - **Notes:** WRAS approved Enhance the reliability and safety of your unvented water systems with the PREL107020 Potable Water Pressure Relief Valve – the essential component for effective pressure management.
