Reliance RWC 103 Series Pressure Relief Valve With Gauge Port 15mm x 15mm 3 Bar - PREL103005

Introducing the Resideo FV300 Float Controlled Filling Valve, an essential solution for water supply systems in both industrial and commercial applications. This valve is designed for efficient filling of reservoirs, tanks, and cisterns. Its operation is managed through a float valve linked to the main storage medium via impulse link pipework. To prevent continuous filling, the valve features a pilot valve that can be finely adjusted, allowing for varying differential fill levels that control the valve’s opening and closing mechanism.

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.
