Vaillant Diverter Valve 252457

Vaillant Turbo Max Plus Diverter Valve (252457)

The Vaillant Diverter Valve (Part No: 252457) is a critical hydraulic component used in combi boilers to manage the flow of primary heated water. It acts as a directional switch, channeling hot water either to the central heating circuit (radiators) or to the domestic hot water circuit (via the secondary heat exchanger). This genuine replacement part is essential for ensuring that hot water is delivered instantly to taps when required, without bleeding heat into the radiators during summer use or failing to provide hot water during the winter.

• Dual-Circuit Switching: Ensures precise transition between heating and hot water modes based on system demand.

• High-Durability Seals: Engineered to resist internal leaks and "by-passing," which can lead to lukewarm water or warm radiators when only hot water is requested.

• Robust Construction: Manufactured to withstand the constant mechanical movement and high-pressure environment of Vaillant’s hydraulic blocks.

• OEM Reliability: Designed specifically for the TurboMax and EcoMax ranges to ensure perfect alignment with existing pipework and actuators.
