NABIC 500 High Lift Safety Valve

**Product Description: Reliance Water Controls (RWC) TPR15 Pressure and Temperature Relief Valves** The Reliance Water Controls (RWC) TPR15 Pressure and Temperature Relief Valves are expertly designed compact units that safeguard against the risks of over-pressurisation in unvented hot water systems. Such over-pressurisation can occur if temperature or pressure controls fail. These valves are specifically engineered to be installed at the upper section of a hot water cylinder, where the highest temperatures in the system are typically found. When the temperature exceeds 95°C, the wax mixture within the temperature probe element expands, lifting the valve off its seat and allowing water to escape, thereby relieving pressure within the cylinder. Additionally, the valve remains closed in the event of rising water pressure without a corresponding temperature increase. It will only open once the pre-set pressure threshold of the relief mechanism is reached, effectively releasing any excess pressure. Certain models come with a PTFE coating on the MBSP inlet thread, which streamlines the installation process, saving you valuable time. **Key Features and Benefits:** - Provides protection against temperatures exceeding 95°C - Prevents over-pressurisation in hot water systems - Twist-top cartridge design allows for easy servicing - Available in a range of pressure settings and probe lengths - Some models include a PTFE coating for enhanced installation efficiency **Specification:** - **Size:** 15mm x 15mm - **Connections:** Compression Inlet x Compression Outlet - **Materials:** Brass - **Medium:** Hot water only - **Set Pressure (Set & Locked):** 7 Barg - **Temperature Relief:** +90 to 95°C - **Discharge Capacity:** 10kW - **Probe Length:** 200mm - **Product Code:** PTEM550953 - **Notes:** Long probe, WRAS approved Enhance the safety and efficiency of your hot water system with the RWC TPR15 Pressure and Temperature Relief Valves – the trusted choice for reliable temperature and pressure control.

**PREL107015 Potable Water Pressure Relief Valve** The PREL107015 Potable Water Pressure Relief Valve is designed to effectively manage over pressurisation in unvented cold water systems. Part of the esteemed Reliance Valves 107 Series, this valve serves as a crucial safety mechanism, ensuring the protection of your unvented cylinder from excess pressure. When the system pressure surpasses the pre-set limit, the valve automatically activates, lifting off the seat and allowing water to discharge to waste. This automatic response positions the valve as the first line of defence in safeguarding your system's integrity. Available with adjustable pressure settings ranging from 3.5 to 6 bar, the PREL107015 valve offers multiple connection sizes to facilitate a seamless installation process, enhancing its versatility for various applications. ### **Features and Benefits:** - **Advanced Diaphragm Design:** Provides improved resistance against scale buildup. - **Reliable Protection:** Safeguards your system from over pressurisation. - **Flexible Installation Options:** Multiple connection sizes to suit diverse setups. - **Adjustable Pressure Range:** Set relief pressure available from 3.5 to 6.0 bar. - **Cold Water Use Only:** Specifically designed for cold water applications. ### **Specifications:** - **Size:** 1/2" x 1/2" - **Connections:** BSP Male Inlet x BSP Female Outlet - **Materials:** Hot pressed DZR Brass - **Medium:** Water - **Set Pressure:** 6 Barg - **Temperature Resistance:** Up to +110°C - **Product Code:** PREL107015 - **Notes:** WRAS approved This reliable Potable Water Pressure Relief Valve is essential for maintaining a safe and efficient unvented system, providing peace of mind through its robust design and proven performance. *For optimal performance in your cold water systems, trust the PREL107015 valve for unparalleled safety and reliability.*
