Self-reliance type flow control pneumatic valve type selection

the national patent no. :. (counterfeit will investigate)
ZLF type (ZL - M self-reliance type pneumatic flow control valve (self balance type pneumatic valve is a kind of intuitive easy flow adjusting control device, the network application of the pneumatic valve can be set according to the design flow rate directly, pneumatic valve can be in under the action of water, automatic eliminate the remainder of the pipeline pressure head and flow rate deviation caused by pressure fluctuation, no matter what the system pressure change all the set flow rate unchanged, the pneumatic valve is finished at one time, these features make the network flow control to the net work into a simple flow distribution, effectively solving the hydraulic imbalance between the network.
