Reliance RWC 5000 Litre Aquasystem Potable Expansion Vessel Pre Set 4 Bar - XVES050220

The CONCOA 304 Series is a three-port, chrome-plated brass, single-stage point-of-use regulator designed for high-purity, non-corrosive, or liquefied gases (up to grade 5.5). It provides secondary or final-line pressure control, reducing delivery pressure in a single step. Its durable construction and high-purity compatibility make it a cost-effective solution for applications that can tolerate minor outlet pressure fluctuations as cylinder supply decreases. Maximum inlet pressure is 3000 PSIG (210 BAR) or higher, depending on configuration.

The Reliance Valves Aquasystem Stainless Steel Expansion Vessel is specifically designed for heating applications. Available in capacities ranging from 2 litres to 5000 litres and with maximum pressure ratings between 8.0 and 10.0 bar, these vessels feature replaceable membranes. The Aquasystem range allows for servicing on-site, ensuring that water does not come into contact with the steel expansion vessel shell, which helps to prevent internal corrosion and extend the vessel's lifespan.

Features and Benefits:

• Durable stainless steel bolted flange that prevents corrosion.
• Extra-wide membrane opening to minimise noise caused by restricted flow.
• Internal membrane design eliminates water contact with the steel shell, thus preventing internal corrosion.
• A comprehensive range from 2 to 5000 litres suitable for various applications.
• All models come with replaceable membranes for convenient servicing without removal.
• Pre-charge valve included for easy topping up of air pressure.
• Designed exclusively for heating applications.

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.
