Baxi Cartridge Motor 720064401 & 720778601

Baxi Cartridge Motor (720064401 & 720778601) The Baxi Cartridge Motor (also referred to as the Diverter Valve Cartridge) is a vital internal component of the hydraulic manifold. It works in direct synchronization with the actuator motor to physically shift the flow of water between the central heating circuit and the plate heat exchanger for domestic hot water. This part is a genuine replacement for part numbers 720064401 and 720778601, designed to ensure smooth and reliable switching in modern Baxi and Potterton systems. Fluid Control Precision: Ensures that the boiler can rapidly transition between heating and hot water demands without internal "bleeding" or performance loss. Reinforced Seals: Features advanced O-ring technology and internal gaskets built to withstand the high temperatures and pressures of modern ERP-rated systems. Corrosion Resistance: Constructed from high-durability materials that resist the buildup of magnetite and limescale, common causes of sticking valves. Direct Mechanical Fit: Engineered for a perfect fit within the 3-way valve body, restoring the mechanical integrity of the hydraulic block.
