Resideo Braukmann SV300 Pilot Operated Safety Valve

The Altecnic / Caleffi 253 Solar Safety Valve - 253046 is designed to regulate pressure within the primary circuits of solar heating systems. This valve is specifically chosen based on the required set pressure. As pressure increases within the system, the valve activates when the discharge pressure is reached, releasing excess pressure to the atmosphere. This vital function helps prevent potential damage to solar collectors and other system components caused by excessive pressure levels.

The PREL102111 Reliance Water Controls (RWC) 102 Series potable water pressure relief valve is designed to efficiently discharge water from the system at a specified pressure in the event of cold water over-pressurisation within an unvented cylinder. The Reliance Valves 102 Series Potable Water Pressure Relief Valves serve a crucial role in safeguarding an unvented system from the dangers of over-pressurisation. Each valve is pre-set and securely locked to a specific pressure; should the system exceed this threshold, the valve will lift off its seat, allowing water to discharge safely to waste. This essential safety device is the first line of defence in any unvented system. These pressure relief valves feature a robust single-piece cartridge and are available in various pressure settings, ranging from 3.5 to 8 bar, along with multiple connection sizes for versatile installation.

**Features and Benefits:**

• Quick and easy removal of the single-piece cartridge for hassle-free cleaning or replacement.
• Innovative diaphragm design enhances resistance to scale build-up.
• Provides reliable protection against over-pressurisation.
