Performance of static balance valve

2. Excellent cut-off function;

3. Display the number of open circles, accurate to110;

4. The theoretical flow characteristic curve is equal percentage (approximate), and the actual flow characteristic is linear when the valve weight is 30-50%;

5, with the lock function, non-property management personnel can not change the setting state;

6. The pressure and flow adjustment is convenient and effective, and the matching intelligent instrument can display the working pressure difference and flow conveniently, and guide and record the balance adjustment scheme;

7, PTFE seal, reliable sealing performance, long service life;

8. According to the opening percentage and the pressure difference before and after the valve, the flow through the valve can be calculated;

9. The internal parts are made of stainless steel and copper alloy, which has strong corrosion resistance;

10. There is no need to reserve operating space for internal promotion valve stem;

1 1, valve body material: DN 15-DN300 is gray cast iron; DN350-DN600 is carbon cast steel; DN 15-DN32 is a forged copper alloy.
