The NMB 24V DC 3-Way Valve Motor is a high-quality motorized actuator that controls the flow direction between the domestic hot water and heating circuits in combi boilers. This model stands out with its durable construction, quiet operation and long-lasting NMB-MAT motor technology. It is fully compatible in particular with Viessmann Vitodens 050 and Bosch – Buderus – Junkers – Worcester combi boilers.
The 3-way valve motor provides the changeover between the domestic hot water (tap) and heating (radiator) circuits of the combi boiler. If the motor fails, the boiler can only operate on one circuit. Therefore, replacement with a genuine NMB 24V DC motor is recommended.
Yedepa supplies genuine NMB-MAT 3-way valve motors with warranty. All products have passed quality control tests and are shipped safely in protective packaging.
