Hydraulic Balancing Valve
Hydraulic balance is necessary to avoid the following problems:
1. Some rooms almost never achieve the desired room temperature or are not cooled sufficiently. This problem especially arises in case of influence of other heat sources.
2. After changing over from low temperature to heating operation, it takes time to heat the parts in the system.
3. Indoor temperature changes, especially in the case of small demand, there is a greater possibility of this situation.
4. Consume more energy
It is unusual if the above problem happens.
The flow Distribution of Hydraulic Balancing Valve
If the drag in some parts of the piping is unbalanced, it will lead to unbalanced distribution of flow. The disposal to this problem is to install a Balance Valve in the piping and use a specific adjusted instrument to balance the drag in the system.
The illustration shows that the pump has to produce a differential pressure at least ΔPtotal to guarantee a sufficient supply t…
