**Product Description: RWC FVMX Pressure & Temperature Relief Valve** The Reliance Water Controls (RWC) FVMX Pressure & Temperature Relief Valve is an essential device designed to discharge water, thereby preventing damage to hot water cylinders caused by excessive temperature or pressure. The FVMX series of pressure and temperature relief valves offers high-capacity protection, safeguarding your system from over-pressurisation and extreme temperatures exceeding 95°C, which may occur in unvented hot water systems if the input temperature or pressure controls malfunction. These valves are specifically engineered for installation directly onto the upper sections of hot water cylinders—where the highest temperatures are found. In the event of an unsafe rise in pressure or temperature, the valve will lift off its seat, releasing water safely to waste and alleviating the stress within the cylinder. The larger FVMX valves are particularly well-suited for commercial applications, providing robust protection in demanding environments. **Key Features and Benefits:** - **High Capacity Protection**: Ideal for both domestic and commercial applications, ensuring safety and efficiency. - **Temperature Safety**: Effectively protects against temperature surges above 95°C. - **Prevention of Over-Pressurisation**: Maintains system integrity and safety. - **Lever Style Easing Mechanism**: Facilitates easy operation and maintenance. - **Variety of Connection Sizes**: Available in different sizes to fit various installations. **Specifications**: - **Size**: 3/4" x 3/4" - **Connections**: BSP Male Inlet x BSP Female Outlet - **Materials**: Brass - **Medium**: Hot water only - **Set Pressure (Set & Locked)**: 7 Barg - **Temperature Relief**: +90 to 95°C - **Discharge Capacity**: 25kW - **Probe Length**: 195mm - **Product Code**: PTEM600001 - **Notes**: WRAS approved Ensure the safety and efficiency of your unvented hot water system with the Reliance Water Controls FVMX Pressure & Temperature Relief Valve, the perfect blend of reliability and performance for any hot water setup.

The CONCOA 432 Series six-port, dual-stage cylinder regulator provides stable pressure control for toxic, non-corrosive, and ultra-high purity gases in laboratory and industrial settings. Dual-stage design minimizes pressure fluctuations from cylinder depletion. Features include metal-to-metal diaphragm seal, CAPSULE® seats with 360° filtration, cleanroom assembly, helium leak-checked integrity, pipe-away relief, and captured vent bonnet. Constructed from 316L stainless steel body with chrome-plated brass bonnet, PCTFE/PTFE seats, 10-micron stainless steel filter, Cv 0.1, 1/4 in FNPT ports, and 2 in gauges. Rated up to 3000 PSIG (3500 or 4500 PSIG optional), temperature range -40°F to 140°F (-40°C to 60°C). Conforms to CGA G-4.1, ANSI/ASME B40.1, PED 2014/68/EU, and CRN OH5216.

The 4925 and 4925G valves feature robust ductile iron bodies with stainless steel discs, fully lugged for secure installation, rated PN25, and suitable for -10°C to 120°C. Lever or gearbox operation is available, with an extended size range and bi-directional dead-end service at 25 bar without downstream backing flanges. Designed for Group 2 liquids, flanges conform to BS EN1092-2, face-to-face to BS EN558, with mounting per ISO 5211 and tested to BS EN12266-1.
