Self Supporting Flow Balance Valve
Product overview
The ZL47F self-operated flow balancing valve is mainly composed of an automatic valve flap and a manual valve flap. Using the automatic pressure change of the medium as power, it automatically adjusts the balance of the flow of each branch to accurately and stabilize the flow, and also has kinetic energy such as opening indication, locking, and closing. It is suitable for flow control of non-corrosive media such as heating and air conditioning. One-time adj-ustment 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 users, overcome the "uneven cooling and heating", and improve the room temperature qualified 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 economic operation;
4. Digital display device is used to directly set the opening of manual control valve to determine the flow rate, and the intelligent instrument is used for one-time debugging.
