Thermostatic Mixing Valve
TVM-W
Description
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).
- TVM-W “Low lead brass” valves meet the
new regulations enforced by the European
Drinking Water Directive that comes into
effect in December 2013.
Main data:
• Setting temperature in the range 35 … 70 °C
• Preset and locked at 50 °C
• Locking function locks the set temperature
• DN 20 and DN 25
• Shuts off flow if the hot or cold supply fails
• Maintains the temperature by varying supply
conditions
• integrated non-return valves
