Reliance RWC 102 Series Pressure Relief Valve 1/2" x 1/2" M x F 6 Bar - PREL102042

The Altecnic / Caleffi 313 Relief Valve with Gauge (Product Code: 313560) is an essential component for domestic hot water systems and heating setups. Designed to safeguard hot water cylinders and boilers, this valve is tailored to ensure optimal safety by releasing excess pressure. Upon reaching the designated discharge pressure, the valve automatically opens, venting to the atmosphere and preventing hazardous pressure levels that could jeopardise the boiler, hot water storage cylinder, and nearby personnel. This model is supplied complete with a built-in pressure gauge for added convenience and monitoring.

**Gate Valves - Reliable Solutions for On-Off Services** Gate valves are expertly engineered for efficient on-off service applications. Comprising a robust Body, Bonnet, Gate, externally threaded Stem, and a Yoke with a rising Stem that features a Non-Rising Handwheel, these valves offer exceptional functionality. They come equipped with an integral seat as standard, with options available for renewable seats, as well as an open and closed indicator complete with a lockable handwheel. **Key Features of Gate Valves** Gate valves provide a positive shutoff mechanism with minimal pressure drop, making them ideally suited for regulating the flow of liquids or gases across diverse applications. Their durable construction and straightforward design also enhance maintenance ease, ensuring long-term reliability and performance. These valves can be operated either manually or through automated systems such as motors, solenoids, and actuators. When the gate is closed, it completely obstructs flow, while opening the gate permits unrestricted fluid passage, ensuring effective control over fluid dynamics. **Material Specifications** - **Body/Bonnet:** NAB (ASTM B148 C95800) - **Stem:** NAB (ASTM B150 C63200) / MONEL (ASTM B865 N05500) - **Bonnet Joint:** SS-136 + Graphite - **Handwheel:** ASTM A351 CF8M **Technical Specifications for #150 Series** - **Design Standard:** API 600 / ISO 10434 / BS 1414 - **Size Range:** DN50 to DN600 - **Flanges:** ASME B16.5 #150 - **End to End Dimensions:** ASME B16.10 #150 - **Testing Standards:** EN 12266-1, API 598 - **Maximum Pressure:** 19 BAR - **Minimum Temperature:** -29°C - **Maximum Pressure at Higher Temperature:** 7.9 BAR - **Maximum Operating Temperature:** 260°C - **Material Test Certification:** BS EN 10204-3.1 **Technical Specifications for #300 Series** - **Design Standard:** API 600 / ISO 10434 / BS 1414 - **Size Range:** DN50 to DN600 - **Flanges:** ASME B16.5 #300 - **End to End Dimensions:** ASME B16.10 #300 - **Testing Standards:** EN 12266-1, API 598 - **Maximum Pressure:** 49.6 BAR - **Minimum Temperature:** -29°C - **Maximum Pressure at Higher Temperature:** 20.6 BAR - **Maximum Operating Temperature:** 260°C - **Material Test Certification:** BS EN 10204-3.1 **Why Choose Our Gate Valves?** Opt for our gate valves for their unmatched reliability and ease of maintenance.

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.

Features and Benefits:

• Protects against temperatures exceeding 95°C
• Prevents over-pressurisation for enhanced safety
• Twist top cartridge design allows for straightforward servicing
• Available in various pressure settings and probe lengths
• Some models include a PTFE coating for easier installation
