CONCOA 315 Series Regulator

**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 PREL104017 High Capacity Potable Water Pressure Relief Valve is designed to safely discharge water from the system when cold water over-pressurisation occurs in an unvented cylinder. This high-flow valve suits larger capacity systems, protecting them from the risks associated with excessive pressure. The Reliance Valves 104 Series High Capacity Potable Water Pressure Relief Valve features a pre-set and locked pressure setting; if the system exceeds this limit, the valve will lift from its seat, allowing water to discharge safely into the waste system. The outlet connection is one size larger than the inlet, ensuring that the valve can manage a high-capacity discharge effectively. This valve acts as the primary safety device in an unvented system. Various pressure settings are available, ranging from 3.5 to 8 bar, along with multiple connection sizes to facilitate flexible installation.
