A ZL-4M self - operated flow control valve product introduction
ZL-4M (ZL47F) series self-reliant flow control valve is a kind of automatic constant flow hydraulic balancing valve. The flow rate can be set as required and the flow rate through the valve is kept constant. ZI-4M self-reliant flow control valve is applied in central heating, central air conditioning and other water systems, so that the flow regulation of the pipe network can be completed in one time, and the network adjustment work can be turned into simple flow distribution. The ZI-4M self-reliant flow control valve eliminates the redistribution of flow when the heat source is switched and effectively solves the hydraulic imbalance of the pipe network.
Two ZL-4M self - operated flow control valve performance and characteristics
1. Flow can be set according to design or actual requirements, which can automatically eliminate the fluctuation of pressure difference of the system and keep the flow constant.
2, to overcome the uneven phenomenon of cold and hot system, improve the quality of heating (cooling).
3. Completely solve the contradiction between large pressure difference near end and small pressure difference far end.
4, reduce the system circulation water, reduce the system resistance.
5, reduce the design workload, do not need to carry out the complicated hydraulic balance calculation of the pipe network.
6, the pipe network layout is simple, do not need to use the same program layout, reduce the cost of pipe network, reduce maintenance costs.
7. Reduce the difficulty of network adjustment and change the complex network adjustment work into simple traffic distribution.
8, exempt from the multi-heat source pipe network heat source switch flow redistribution work.
9, with the opening degree locking function.
10. The displayed flow value of the whole circle is the test value.
11, the use of advanced technology diaphragm, theoretical error is zero. And can withstand 0.8MPa pressure difference.
Three ZL-4M self-reliant flow control valve technical parameters
1. Nominal pressure 1.6mpa;
2 medium temperature 0-150℃
3. Working pressure difference range 0.02-0.4mpa(2-40mh 2o);
4. The structure length conforms to the size of the globe valve in gb/t12221;
5. Flow relative error ≤± 5%
