Product Usage
One-time adjustment before operation can make the system flow automatically constant at the required set value.
Product Features
1. The system flow can be automatically balanced at the required set value;
2. It can automatically eliminate the hydraulic imbalance caused by various factors in the water system, maintain the flow required by the user, overcome the "uneven heating and cooling", and improve the room temperature qualification rate of heating and air conditioning;
3. It can effectively overcome the bad operation mode of "large flow and small temperature difference", improve the energy efficiency of the system, and realize economical operation.
