Highlight: static balancing valve
Product introduction:
The new digital lock balance valve produced by our company is a new type of energy-saving valve with special functions. As the valve is provided with digital display and digital locking device, can be directly adjusted to any position, and pressure measurement valve for flow measurement.
This valve is mainly used in industrial and civil building heating pipe network system, has the good flow characteristic, can adjust the pressure drop and flow rate accurately, can reasonable distribution of flow, implementation flow quantitatively, can effectively solve the heating (air conditioning) to room temperature uneven and the problems existing in the system, as long as in the selection and user entry fitted with appropriate specifications of digital locked balance valve, And a special intelligent instrument for one-time debugging after locking, the total water control system in a reasonable range, so as to overcome the "large flow, small temperature difference" unreasonable phenomenon. Therefore, this product is an ideal product in heating system. The application of this valve can achieve the dual effect of liquid balance and energy reduction in pipe network.

Product features:
1. ideal adjustment performance;
2. Excellent cut-off function;
3. accurate to 1/10 turn of the open state display;
4. The theoretical flow characteristic curve is equal percentage characteristic curve;
5. national patent opening and closing locking device;
6. corresponding to each whole circle has a fixed flow coefficient, debugging as long as the pressure difference between the two ends of the valve is measured, it can be convenient to calculate
Discharge flow through the valve
