The Reliance CORE215002 pressure relief valve core unit is designed for use in unvented hot water systems, providing essential protection by safely discharging excess pressure when system limits are exceeded. Featuring 22mm and 3/4" connections with a 4 port configuration, this 6 bar rated valve core unit supports efficient system operation and safety compliance.
Pressure relief valves are critical safety components that prevent excessive pressure build-up within sealed systems, protecting cylinders, pipework, and associated components from potential damage or failure. The 4 port core unit design allows integration within multi-functional valve assemblies, commonly found in unvented cylinders and combination control packs. Over time, internal components can become affected by scale, wear, or repeated operation, which may reduce performance or cause leakage. Replacing the core unit restores proper pressure control, maintains system safety, and ensures continued compliance with installation standards. Installation should always be carried out by a suitably qualified professional in accordance with current regulations.
