Hattersley Fig 973G PN16 Double Regulating Valve - Gearbox Operated

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.

• Protects against temperatures exceeding 95°C
