4 diaphragm epdm buried fiber

5 the stainless steel screw


Technical parameter

1.pressure level 1.6MPA,2.5MPA

2.Medium temperature 0-150℃

3.Working pressure difference 20-600 KPA

4.Products meet the CJ/T179-2003 industry standards


Performance and features

1. Can be set according to requirements of the design or the actual flow, the system can automatically eliminate the differential pressure fluctuation, the flow rate unchanged

2. The phenomenon of uneven and customer service system, improve the quality of heating (cooling)

3. Thoroughly solve the proximal differential pressure big, distal small pressure difference

4. Decrease the water circulating system, reduce the resistance

5. Reduce the workload of design, don't need to work on pipe network for the complex hydraulic balance calculation

6. Decrease the difficulty of the network turn complex net work simplified as simple distribution of shunt

7. From the flow of heat pipe heat source switch more redistribution

8. Flow display values are random calibration flow test bench
