GESTRA return-temperature control valves BW
No outside energy or maintenance required
The cost efficiency of heating systems depends to a great extent on how well the heating medium stays at the right temperature for operation.
This can be helped by BW return-temperature control valves, which keep the set return temperature constant. The heating medium is only discharged after it has cooled down to the set closing temperature. This thrifty operation reduces running costs.
