The Worcester Bosch 87161034230 Bosch Valve is a genuine replacement central heating control valve designed to regulate the flow of heated water from your boiler’s heat exchanger into the central heating circuit. This precision-engineered valve plays a key role in directing heat where it’s needed when there is a demand for space heating. By opening and closing in response to signals from the boiler’s control system, it helps maintain stable radiators, accurate temperature delivery and efficient energy use. A malfunctioning CH valve can cause poor heat distribution, noisy operation, uneven radiator temperatures or fault codes, so fitting the correct OEM-specified valve is essential for dependable performance.

This Bosch valve is compatible with Worcester Bosch Junior, Si and CDi series boilers that reference part number 87161034230 in their technical documentation. To ensure correct fitment and reliable operation, always verify that the part number matches your existing component or consult your boiler’s service information before installation, as valve designs and port sizes vary between models and system configurations.

Supplied ready for direct replacement, the 87161034230 Bosch CH Valve integrates with the boiler’s existing pipework and actuators when installed by a qualified engineer. Choosing this genuine Worcester Bosch component helps restore proper central heating flow control, supports efficient heat distribution and contributes to consistent, trouble-free operation in compatible Junior, Si and CDi boilers.
