The TVM-W is a self-acting mixing valve, which provides mixed water at a constant temperature. It is used for instant supply of water at a required temperature in domestic hot water applications. The quick reaction of the thermostatic elements ensures accurate temperature control. It is suitable for single outlets (e.g. baths, basins, showers and bidets) or small numbers of grouped outlets. Its robust and non-complex construction provides superior reliability, improved safety, energy efficiency and user comfort. If the cold supply fails, a total and fast flow shut-off results in greater safety for the enduser. Simplified design and construction, with fewer components, ensures superior reliability, longevity and safety. The TVM-W ensures a high level of protection from scalding, which is important especially in hospitals, schools or multi family houses (e.g. in case of legionella disinfections).
