The Reliance Water Controls (RWC) TPR15 Pressure & Temperature Relief Valves are compact, yet highly effective, valves designed specifically to protect your unvented hot water system from the dangers of over-pressurisation. This critical safety feature is essential, as over-pressurisation can occur if the input temperature or pressure controls fail. The valves are strategically designed to be installed at the top of a hot water cylinder, where the highest temperatures are typically found. Should the temperature exceed 95°C, the wax mixture in the temperature probe's element will expand, lifting the valve from its seat and allowing excess water to be discharged safely. Additionally, if water pressure increases without a corresponding temperature rise, the valve remains closed until the pre-set pressure of the relief mechanism is reached, at which point it opens to relieve the excess pressure. Some models are equipped with a PTFE coating on the MBSP inlet thread, facilitating a quicker and more efficient installation process.

Features and Benefits:

• Protects against temperatures exceeding 95°C
• Prevents over-pressurisation in hot water systems
• Innovative twist-top cartridge design for straightforward servicing

Ensure the safety and reliability of your hot water system with the RWC TPR15 Pressure & Temperature Relief Valves, an essential component for maintaining optimal performance and peace of mind.

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 water systems as water is heated and expands. These expansion vessels play a crucial role in maintaining safe operating levels, preventing excessive pressure build-up in both sealed heating and cold water systems. Each vessel features a replaceable membrane that safeguards against corrosion and contamination, ensuring that the water remains safe for human consumption. The inclusion of a replaceable membrane also facilitates easy servicing of the vessel without requiring removal, allowing for quick maintenance in situ.

Features and Benefits:

• Stainless Steel Bolted Flange: Resists corrosion for enhanced durability.
• Extra Wide Membrane Opening: Reduces noise caused by restricted flow for a quieter operation.
