Reliance RWC TPR15 Pressure & Temperature Relief Valve 1/2

Reliance RWC TPR15 Pressure & Temperature Relief Valve 1/2" x 15mm 6 Bar - PTEM550857

The Reliance Water Controls (RWC) TPR15 Pressure and Temperature Relief Valves are compact devices meticulously engineered to safeguard against overpressurisation within unvented hot water systems. This crucial protection comes into play if the temperature or pressure controls fail. These valves are designed to be installed at the upper section of a hot water cylinder, where the highest temperatures can typically be found. In the event that the system temperature exceeds 95°C, the wax mixture within the temperature probe's element expands, causing the valve to lift off its seat and release water to waste. This process effectively alleviates excess pressure within the cylinder. Additionally, if the water pressure increases without a corresponding rise in temperature, the valve remains closed until it reaches the set pressure of the relief mechanism, at which point it opens to relieve the excess pressure. Certain models feature a PTFE coating on the MBSP inlet thread, significantly enhancing installation efficiency. ### Features and Benefits: - Provides protection against temperatures exceeding 95°C - Prevents dangerous overpressurisation - Twist-top cartridge design facilitates easy servicing - Available in a variety of pressure settings and probe lengths - Some models include a PTFE coating for added convenience ### Specification: - **Size:** 1/2" x 15mm - **Connections:** BSP Male Inlet x Compression Outlet - **Materials:** Brass - **Medium:** Hot water only - **Set Pressure (Set & Locked):** 6 Barg - **Temperature Relief:** +90 to 95 °C - **Discharge Capacity:** 10 kW - **Probe Length:** 95 mm - **Product Code:** PTEM550857 - **Notes:** Includes PTFE, WRAS approved Ensure the safe operation of your unvented hot water system with the RWC TPR15 Pressure and Temperature Relief Valves, an essential investment for any modern heating system.

Reliance RWC 100 Series Pressure Relief Valve 3/4

Reliance RWC 100 Series Pressure Relief Valve 3/4" x 1" F x F 3 Bar - PREL100014

**PREL100014 High Capacity Sealed Heating System Pressure Relief Valve** The PREL100014 High Capacity Sealed Heating System Pressure Relief Valve is designed to safely discharge water from the system at a predetermined pressure during instances of over-pressurisation—particularly suitable for larger capacity systems. Manufactured by Reliance Valves, the 100 Series Pressure Relief Valves are crafted from hot pressed brass and are primarily employed to protect closed-circuit wet heating systems against excessive pressure. Key features include an outlet that is one size larger than the inlet, ensuring high discharge flow rates. The valve features a separate seal seating from the diaphragm, enhancing resistance to scaling, and a cover made from OT58 brass. Available in various sizes to accommodate most installations, it operates within a pressure range of 2.5 - 5.0 bar, with the specified response pressure conveniently indicated on the twist cap. The appropriate valve size is determined by the heat output of the boiler, as detailed in the maximum heating capacity table. ### Features and Benefits: - **High Flow Design:** Optimised for larger capacity systems. - **Enhanced Discharge Capacity:** The outlet is larger than the inlet for superior discharge rates. - **Overpressure Protection:** Safeguards wet heating systems against excessive pressure. - **Improved Scaling Resistance:** Diaphragm design enhances resistance to scale build-up. - **Easy Maintenance:** Cartridge design allows for hassle-free servicing and replacements without the need to reset response pressure. - **Versatile Pressure Range:** Set pressure range from 2.5 - 5.0 bar accommodates diverse system requirements. - **Increased Discharge Capability:** High lift design for enhanced discharge performance. - **Application Specific:** Suitable exclusively for heating applications. ### Specifications: - **Size:** 3/4" x 1" - **Connections:** BSP Female Inlet x BSP Female Outlet - **Materials:** Hot pressed DZR Brass - **Medium:** Water - **Set Pressure:** 3 Barg - **Temperature:** +140 °C - **Product Code:** PREL100014 - **Notes:** WRAS approved Ensure the reliability and efficiency of your heating system with the PREL100014 High Capacity Sealed Heating System Pressure Relief Valve—designed to protect and enhance your installation's performance.
