Biasi Diverter Valve Repair Kit (7224763)
The Biasi Diverter Valve Repair Kit (Part No: 7224763) is a comprehensive internal component overhaul kit engineered for the plastic-bodied hydraulic manifolds used extensively in high-efficiency condensing combination boilers. This targeted service kit includes the central cartridge assembly, internal shuttle stems, dynamic O-rings, and specialized seals. By replacing these primary internal wear components, the kit restores smooth mechanical transitions within the diverter assembly, allowing the boiler to accurately isolate and redirect primary heated water between the central heating circuit and the domestic plate heat exchanger.
Internal Flow Corrections: Rebuilding the core manifold block addresses common faults such as central heating "bleed" (radiators warming up during summer tap use) and internal bypass tracking.
Low-Friction Operation: Features high-tolerance internal sliders designed to glide smoothly within the plastic hydro-block assembly, preventing mechanical sticking and erratic hot water operation.
Premium Elastomeric Seals: Equipped with high-grade EPDM O-rings engineered to withstand the chemical additives, aggressive magnetite sludge, and severe thermal cycles typical of modern sealed heating systems.
Cost-Efficient Restoration: Provides an effective alternative to replacing the complete hydraulic block assembly, saving substantial parts costs and significantly reducing installation labor time. Compatible Models:
