Monobloc Mixer Tap With Aerator Nozzle - 900115

The Reliance Water Controls (RWC) TPR22 Pressure & Temperature Relief Valves are compact relief valves specifically designed to safeguard against over-pressurisation within unvented hot water systems. Should the input temperature or pressure controls fail, these valves provide essential protection. They are optimally installed at the upper section of a hot water cylinder, where the highest temperatures are typically found. When the system exceeds 95°C, the wax mixture within the temperature probe element expands, lifting the valve off its seat and allowing water to discharge, thereby alleviating the pressure within the cylinder. In instances of increased water pressure without a corresponding temperature rise, the valve will remain closed until the designated relief mechanism pressure is reached, at which point it will open to release the excess pressure. Certain models feature a PTFE coating on the MBSP inlet thread, streamlining the installation process and saving valuable time.

The AURA EXZ is a sub-atmospheric back-pressure regulator specifically designed to provide adjustable relief for excess positive pressure in vacuum systems, which can occur due to pressure build-up or upstream sample injection. Featuring a proprietary hybrid spring system and an oversized dual-surface diaphragm, the AURA EXZ guarantees exceptional precision, stability, and repeatability in its performance. With multiple seat material options available, this regulator effectively eliminates any unwanted reactions with process media, allowing for accurate throttling of excess pressure and helping to maintain optimal process conditions. Each AURA EXZ regulator is meticulously assembled in a Class 100 cleanroom, complete with all necessary gauges, fittings, and valves. The assembly undergoes thorough cleaning for oxygen service, is 100% helium leak tested, and is subjected to comprehensive flow and function tests to ensure long-term reliability, durability, and leak integrity, even in the most demanding environments worldwide. For applications that involve highly corrosive or aggressive substances, the AURA EXZ can be equipped with Dursan® LS inert coating technology, providing superior resistance to acidic and caustic media compared to traditional exotic alloys. This inert surface not only prevents moisture and media absorption but also ensures consistent performance in sensitive processes. With its precision control, advanced material options, and robust construction, the AURA EXZ is the ideal choice for accurate and reliable excess pressure control in sub-atmospheric applications.

**Stainless Steel Expansion Vessel for Potable Water Applications** Introducing the Reliance Valves Aquasystem Replaceable Membrane Potable Water Expansion Vessels, expertly designed to manage the additional load within your water system during the heating process, when water expands in volume. These expansion vessels play a crucial role in maintaining safe operating levels by averting pressure build-up in both sealed heating and cold water systems. Featuring a replaceable membrane, our vessels prevent water from coming into contact with the steel shell, effectively stopping corrosion and contamination, thus ensuring the water remains safe for human consumption. The replaceable membrane allows for convenient servicing in situ, eliminating the need to remove the vessel for maintenance. ### Features and Benefits: - **Corrosion-Resistant**: The stainless steel bolted flange ensures enhanced durability and corrosion prevention. - **Noise Reduction**: An extra wide membrane opening mitigates noise caused by restricted flow, ensuring a quieter system. - **Internal Protection**: The internal membrane provides a barrier, preventing any water contact with the steel shell and eliminating internal corrosion. - **Comprehensive Range**: Available in sizes from 2 to 5000 litres, catering to all applications. - **Effortless Servicing**: Each unit is supplied with a replaceable membrane, allowing for easy servicing without removal. - **Convenient Pre-Charge**: Equipped with a pre-charge valve for easy topping up of air pressure. - **Hot and Cold Water Compatible**: Suitable for use with both hot and cold water systems. ### Specification: - **Capacity**: 1000 Litres - **Colour**: Red - **Pre-Set Pressure (Bar)**: 4 - **Max Pressure (Bar)**: 10.0 - **Minimum Temperature**: -10°C - **Maximum Temperature**: 99°C - **Height**: 2160mm - **Diameter**: 800mm - **Water Connection**: 2" MBSP - **Product Code**: XVES050170 **Materials**: - Shell: Epoxy Coated - Membrane: EPDM - Bolted Flange: Stainless Steel **Standards and Approvals**: - WRAS approved for capacities 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 Ensure the safety and efficiency of your water system with our high-quality stainless steel expansion vessels, designed for reliability and performance.
