7. Dynamic pressure Balance Valve has three functions, self-reliance type flow valve function, Automatic Balancing Valve function, self-reliance type differential pressure valve function.Pump respectively in three operation modes of different transformation.Flow must be on self-reliance type flow valve function, give priority to with heat source variable flow when using manual balancing valve function, users as the main traffic conversion ChengZiLi type differential pressure valve function, avoid heat supply network frequent replacement of valve, reduce the cost.



1. Double disc structure, unbalanced force is small, compact structure.

2. Automatic constant user pressure difference, absorb the network pressure fluctuations, support controlled system of autonomous regulation.

3. Control the catheter front installation block valves, have automatic eliminate congestion function.

4. Adopt mixed compression technology, stepless adjustment, pressure control general tuning range is big.

5. Differential pressure calibration precision, high precision of adjustment.

6. Adopting outside pressure structure, tear open outfit is convenient.

7. All copper valve, valve core.
