The Worcester 87133060540 Throttle is a genuine replacement hydraulic control component designed to regulate the flow of water within your boiler’s central heating circuit. By providing a precise restriction point, the throttle helps balance system flow, support stable temperatures and ensure smooth operation of pumps and valves. Correct throttling can improve heat distribution and help prevent pressure imbalances, air noise or uneven radiator output. A worn or incorrect throttle can contribute to inefficiencies, unstable flow conditions or nuisance fault codes, so fitting the correct OEM part is important for dependable performance.

This throttle is compatible with specific Worcester and Worcester Bosch boilers that reference part number 87133060540 in their technical documentation. To ensure correct fitment and reliable operation, always verify the part number on your existing component or consult your boiler’s service information before installation, as hydraulic control parts vary between models and system configurations.

Supplied ready for direct replacement, the 87133060540 Throttle integrates with the boiler’s existing pipework and control points when installed by a qualified engineer. Choosing this genuine Worcester Bosch component helps maintain correct hydraulic balance, supports efficient heat transfer and contributes to reliable central heating performance in compatible systems.
