NABIC 520 - Spares Kit

The Altecnic / Caleffi 527 Safety Valve - 527560EST is essential for effective pressure control in heating systems, particularly in heat generators, hot water storage units, and hydraulic systems. This safety valve is designed to open when the preset pressure is reached, discharging excess pressure into the atmosphere to ensure that the pressure in the system remains safely below dangerous levels for both the generator and the installed components. The 527 EST series valves are also fail-safe devices, ensuring reliability of operation even in the event of diaphragm wear or breakage.

The Altecnic / Caleffi 312 Safety Valve - 312405CST is essential for domestic hot water systems, providing vital protection for hot water cylinders and heating systems, including boilers and other components. This safety valve is meticulously selected for its specific set pressure. As system pressure increases, the valve activates once the discharge pressure is reached, releasing excess pressure into the atmosphere. This action safeguards both the boiler and hot water storage cylinder, ensuring safe operational conditions for personnel nearby.

Introducing the Reliance Valves Aquasystem Stainless Steel Expansion Vessel, expertly designed for potable water applications. These replaceable membrane expansion vessels are essential for managing the additional load within water systems as water heats up and its volume expands. By effectively regulating pressure in both sealed heating systems and cold water systems, these vessels ensure safe operational levels and prevent dangerous pressure build-up. Featuring a replaceable membrane, the design prevents water from coming into contact with the steel shell, thereby eliminating issues of corrosion and contamination and keeping the water safe for human consumption. This innovative feature also allows for swift and efficient servicing in situ, so there's no need to remove the vessel for maintenance.

Features and Benefits:

• Durable stainless steel bolted flange to prevent corrosion
• Extra-wide membrane opening to minimise noise caused by restricted flow
• Internal membrane ensures no water contacts the steel shell, preventing internal corrosion
• A comprehensive range available from 2 to 5000 litres, suitable for all applications
• All models come with a replaceable membrane for easy servicing without removal
• Equipped with a pre-charge valve for convenient air pressure adjustments
• Designed exclusively for hot and cold water usage
