Resideo Braukmann D04FM Pressure Reducing Valve - Compression Fitting

**Stainless Steel Expansion Vessel for Potable Water Applications** The Reliance Valves Aquasystem Replaceable Membrane Potable Water Expansion Vessels are expertly designed to accommodate the increased load within a water system as water heats and expands. These expansion vessels play a crucial role in maintaining safe operating levels by effectively preventing pressure build-up in both sealed heating systems and cold water systems. Featuring a replaceable membrane, these vessels prevent water from coming into contact with the steel shell, thereby avoiding corrosion and contamination, ensuring that the water remains safe for human consumption. The replaceable membrane also allows for easy servicing without the need to remove the vessel, enabling quick and efficient in-situ maintenance. **Features and Benefits:** - **Corrosion-Resistant Design:** The stainless steel bolted flange prevents corrosion, ensuring durability and longevity. - **Quiet Operation:** The extra-wide membrane opening helps reduce noise resulting from restricted flow. - **Protective Internal Membrane:** Prevents any direct contact between water and the steel shell to stop internal corrosion. - **Versatile Capacity Range:** Available in sizes from 2 to 5000 litres, suitable for a variety of applications. - **Easy Servicing:** All models come equipped with a replaceable membrane, allowing for servicing without vessel removal. - **Pre-Charge Valve:** Convenient for topping up air pressure. - **Hot and Cold Water Compatibility:** Designed specifically for hot and cold water use only. **Specifications:** - **Capacity:** 24 Litres - **Colour:** White - **Pre-Set Pressure (Bar):** 3 - **Max Pressure (Bar):** 10.0 - **Minimum Temperature:** -10°C - **Maximum Temperature:** 99°C - **Height:** 489mm - **Diameter:** 280mm - **Water Connection:** 3/4" MBSP - **Miscellaneous:** Comes complete with wall bracket and accessories - **Product Code:** XVES050065 **Materials:** - **Shell:** Epoxy Coated Steel - **Membrane:** EPDM - **Bolted Flange:** Stainless Steel **Standards and Approvals:** - WRAS approved for tanks up to 1000 litres - CE marked in accordance with Directive PED 97/23/CE - TÜV Certified - Materials for 1000 - 5000 litre models comply with BS 6920 Enhance your potable water system with the Reliance Valves Aquasystem Expansion Vessel, designed for efficiency, safety, 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.
