Thermostatic mixing valve
VTA370, VTA570
- High flow capacity
- Protection against excess temperatures.
The series VTA370 and VTA570 are the number one choice for heating and cooling applications. The valves provide a scald safe function, which is important in order to protect e.g. under floor heating pips and also the floor itself from to uncontrolled rise of temperature.
