Thermostatic mixing valve
VTG140
- Left or right connection to the UFH manifold
- High kvs value
- Easy setting of the temperature via knob
- Compact design
The VTG140 series are 4-way thermostatic valves dedicated for heating applications with focus on underfloor heating. The special design of the valve allows mirroring the connection to the manifold in an easy way and eliminates the need for additional connection components. The temperature range 20-55°C is convenient for underfloor heating from the start-up of the system to its normal working conditions.
