Worcester Diverter Valve Paddle

Worcester Diverter Valve Paddle (87161068450) The Worcester Diverter Valve Paddle is a fundamental internal component of the hydraulic manifold in Worcester Greenstar boilers. As a genuine replacement part (87161068450), the paddle is the physical gate that moves to direct the primary heated water. When the boiler receives a demand for domestic hot water, the diverter motor pushes this paddle to seal off the central heating circuit, forcing the hot water through the plate heat exchanger. When the demand ends, it returns to the heating position. Switching Precision: Engineered for rapid and total shut-off between the heating and hot water circuits to prevent lukewarm water at the taps. High-Grade Elastomers: Features durable rubberized seals designed to withstand the constant friction and high temperatures of the primary circuit. Reduced Resistance: Designed with a hydro-dynamically optimized shape to minimize flow noise and pressure drop within the manifold. Common Fault Fix: Replacing the paddle is a standard solution for "crossover" issues, where radiators get warm while running a hot tap.
