- Product Overview
ZLF/ZL47F type self flow balance valve or self balancing valve, flow control valve, flow control, dynamic balancing valve, balancing valve, is a simple and intuitive flow regulating control device, self application of the network flow balance valve can be directly set according to the design flow, the valve can be automatically eliminated under the action of water, flow rate deviation in the remainder of the pipeline pressure head and pressure fluctuations caused by, no matter how the pressure changes in the system settings are maintained constant flow, self operated flow balancing valve these features enable network flow control once completed, the net adjustment work for flow distribution is simple, effective solution to the network hydraulic imbalance. Self operated flow balancing valve is mainly used in central heating (cold) and other water systems, so as to make the pipe network flow according to demand, eliminate the hydraulic imbalance of the water system, solve the problem of uneven cooling and heating, and save energy and save electricity 15%-20%.

- product features
The flow can be set according to the design or actual requirements, which can automatically eliminate the pressure fluctuation of the system and keep the flow unchanged.
Overcome the uneven cooling and heating system, improve the quality of heating (cooling).
Thoroughly solve the contradiction of large pressure difference and small pressure difference at the proximal end.
Reduce system circulating water and reduce system resistance.
Reduce the design workload, do not need to pipe network cumbersome hydraulic balance calculation.
Reduce the difficulty of network adjustment, simplify the complex network work into simple flow distribution.
Flow redistribution work without heat source switching of multi heat source network.
The flow display values were calibrated randomly on the test bench, and the flow rate (m3/h) was measured.
