The Worcester 87161424220 Pressure Relief Valve (also referred to by reference 314439) is a genuine safety component designed to protect your boiler’s central heating or hot water system from excessive pressure. This valve automatically opens to release water when system pressure rises above a safe threshold, preventing stress and potential damage to internal components such as pipework, seals, pumps and the heat exchanger. By maintaining correct pressure limits, it helps reduce the risk of leaks, pressure faults and safety shutdowns, supporting safe and reliable operation.

This pressure relief valve is compatible with Worcester and Worcester Bosch boilers that reference part number 87161424220 in their technical documentation. To ensure correct fitment and dependable performance, always verify that the part number matches your existing valve or consult your boiler’s service information before installation, as relief valves and pressure ratings can vary between models and systems.

Supplied ready for direct replacement, the 87161424220 Pressure Relief Valve connects to the boiler’s designated safety outlet and integrates with the system’s pipework when installed by a qualified engineer. Choosing this genuine Worcester Bosch component helps maintain proper pressure control, protect your heating system and contribute to consistent, trouble-free boiler performance.
