Pneumatic flow control valve is mainly used in powder material flow control system. The pneumatic flow control valve adjusts the flow rate by adjusting the opening angle of the flow section of the 

cylindrical valve. Generally used as an on/off valve in conjunction with an electric flow valve. In the actual operation process, the flow rate can be set according to the design or actual working environment

 requirements, which can not only automatically eliminate pressure fluctuations in the system, but also maintain the flow rate unchanged. Moreover, it can overcome the phenomenon of uneven heating 

and cooling in the system and improve the quality of heating (cooling). Thoroughly solve the contradiction between large pressure difference at the proximal end and small pressure difference at the distal

 end. Reduce the circulating water volume of the system and reduce system resistance.

Overcoming the phenomenon of uneven heating and cooling in the system and improving the quality of heating (cooling).

Thoroughly solve the contradiction between large pressure difference at the proximal end and small pressure difference at the distal end.

Reduce the circulating water volume of the system and reduce system resistance.

Reduce design workload and eliminate the need for tedious hydraulic balance calculations on the pipeline network.

Reduce the difficulty of network adjustment and simplify complex network adjustment work into simple traffic allocation.

Exempt flow redistribution during heat source switching in multi heat source pipeline networks.

The displayed flow values are all randomly calibrated on the test bench, with a flow rate of m3/h.
