Vaillant Diverter Valve 011269 I 011289

Vaillant Diverter Valve (011269 | 011289) The Vaillant Diverter Valve Assembly (Part Nos: 011269 or 011289) is a complete, heavy-duty brass hydraulic distribution manifold engineered specifically for early-generation Vaillant TURBOmax combination boilers. This solid brass mechanical valve serves as the central traffic controller for the boiler's primary water circuit. Utilizing an internal diaphragm and pressure-driven shuttle assembly, it responds dynamically to changes in water flow when a hot water tap is opened. The valve instantly shifts positions to seal off the space heating network, diverting the high-velocity, primary heated water exclusively through the secondary domestic plate heat exchanger to ensure immediate hot water delivery. Cross-Circuit Bleed Remediation: Permanently resolves the common system fault where primary heat escapes into the radiators during summer tap use, ensuring 100% of the boiler's thermal output is focused on domestic hot water. Solid Brass Construction: Manufactured from high-grade, commercial brass to deliver superior structural strength, easily resisting internal pitting, micro-fractures, and high-pressure stress over a long operational lifespan. Sludge & Limescale Defiance: Internal tracking channels and moving gates are machined with exact tolerances to maintain smooth mechanical stroke movement, even when exposed to heavy magnetite sludge or hard water scale. Flawless OEM Integration: Designed as a direct drop-in replacement housing that perfectly matches the factory union positions, ensuring a clean, watertight connection with the boiler's original pipework tail configuration.
