3-way Cartouche de vanne De Dietrich 767559200

The 3-way valve cartridge is a replaceable internal component of a three-way valve used in heating systems to direct water flow. This cartridge controls the mixing or diversion of water between circuits, such as between heating and domestic hot water. When the valve fails to operate correctly, replacing the cartridge can restore proper function without replacing the entire valve assembly. It is a practical solution for maintaining efficient system operation.
