Resideo Braukmann BA300 Spares - Inlet Check Valve

Introducing the Reliance Valves Aquasystem Stainless Steel Expansion Vessel, expertly designed for potable water applications. These replaceable membrane expansion vessels are essential for managing excess pressure in water systems as the water heats up and expands. By preventing pressure build-up in both sealed heating systems and cold water systems, these vessels ensure safe operational levels. The internal replaceable membrane safeguards against corrosion and contamination, thereby guaranteeing that the water remains safe for human consumption. Moreover, the design allows for quick and efficient servicing without the need to remove the vessel from its installation.

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.
