COI TECH SLK Type B Safety Valve

**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 Altecnic / Caleffi Relief Valve - Pushfit Inlet - 312007CST is an essential component for domestic hot water systems, designed to safeguard the hot water cylinder and protect heating systems, including boilers and other critical components. This relief valve is available in a selection of set pressures to meet your specific requirements. As system pressure increases and reaches the predetermined discharge pressure, the valve automatically opens, releasing excess pressure into the atmosphere. This function is crucial in preventing hazardous pressure levels that could endanger the boiler, the hot water storage cylinder, and any personnel nearby.
