Ideal Boiler Diverter Valve Cartridge Kit (173967 / KR12024)
The Ideal Diverter Valve Cartridge Kit (Part Nos: 173967 or KR12024) is a targeted internal mechanical overhaul solution engineered for the high-efficiency composite hydraulic manifold blocks utilized across Ideal's prominent Esprit 2 and Isar HE combination boiler lines. This critical maintenance kit features the primary internal spring-loaded cartridge mechanism, reinforced central control rod, dynamic shuttle plates, and a complete layout of precise high-tolerance sealing gaskets. By swapping out these high-wear internal components, the kit re-establishes seamless physical tracking within the hydro-block, letting the boiler cleanly lock down or open water channels to separate the space heating circuit from the domestic hot water secondary plate heat exchanger.
Cross-Circuit Flow Rectification: Repairs the prominent system fault where central heating water drifts into the radiators during summer hot water tap operations, locking the energy focus exclusively onto domestic demands.
Scale-Resistant Internals: Built with advanced low-friction guide stems engineered to counter the sticky accumulation of hard water limescale and floating black iron oxide sludge.
Hermetic Zone Sealing: Outfitted with robust, industrial-grade rubber O-rings designed to maintain tight structural isolation during high-temperature thermal spiking and structural system pressure shifts.
Cost-Efficient Overhaul: Provides a targeted mechanical rebuild that addresses the core points of physical wear, removing the logistical necessity and higher cost of replacing the entire molded hydraulic block.
