FSTCDFA - Forward Acting Rupture Discs

The Altecnic / Caleffi 312 Safety Valve - 312425 is an essential component for domestic hot water systems, designed to safeguard hot water cylinders and heating systems, including boilers and other critical components. This safety valve is chosen based on the specific set pressure required for your system. As pressure increases and reaches the predetermined discharge pressure, the valve opens, allowing excess pressure to escape to the atmosphere. This vital function prevents the internal pressure from escalating to levels that could pose a risk to the boiler, hot water storage cylinder, and the safety of personnel nearby.

The PREL106004 Potable Water Pressure Relief Valve is engineered to discharge water from the system when cold water exceeds a set pressure, ensuring the safe operation of unvented cylinders. The Reliance Valves 102 Series Potable Water Pressure Relief Valves are specifically designed to safeguard unvented systems from over pressurisation. These valves come pre-set and locked to a designated pressure; if the system surpasses this pressure, the valve will lift off its seat, allowing water to discharge safely into the waste system. This is the primary safety device in any unvented system. The pressure relief valves feature a robust single-piece cartridge design and are available in various pressure settings and multiple connection sizes, providing flexibility in installation.

Features and Benefits:

• Quick removal of the single-piece cartridge for easy cleaning or replacement
• Diaphragm design enhances resistance against scale build-up
• Protects against over pressurisation, ensuring system safety
• Multiple connection options for versatile installation
• Configured to relieve pressure starting from 7.5 bar
• Designed exclusively for use with cold water
