Self-flow control valve selection

1. According to the pipe diameter selection.

2. According to the maximum flow and valve flow range selection.

Self-flow control valve installation and commissioning

1. The flow direction of the medium should be the same as the flow direction arrow of the valve body.

2. After installation, set the flow according to the demand of the pipeline in series.

3. Check the pressure drop across the valve is in the working pressure range.

4. As far as possible to avoid the valve in the minimum flow state of work.

Performance and characteristics of self-operated flow control valve

1. According to the design or actual requirements set flow, the system can automatically eliminate the pressure fluctuations, to maintain the same flow.

2. Flow display values are the test bench random calibration flow (m 3 / h).

3. Completely solve the pressure near the end of large, remote pressure small contradictions.

4. To overcome the uneven system of hot and cold, improve heating (cooling) quality.

5. Reduce the design workload, does not require control

6. Reduce the system of circulating water, reduce system resistance.

7. Relieve multi-heat pipe network traffic switching when the redistribution of work.

8. Reduce the difficulty of network transfer, the complexity of network transfer work simplified to a simple traffic distribution.

Self-operated flow control valve technical parameters

1. Medium temperature 0 ~ 150 ℃.

2 working pressure 20-600Kpa.

National Patent No .:.6 (copy must study)

ZLF (ZL-4M) self-acting flow control valve (self-Balancing Valve) is an intuitive and easy flow control device, the valve can be used directly in the pipeline to set the design flow, the valve can be in the role of water , Automatically eliminate the remaining pressure head of the pipeline and pressure fluctuations caused by the flow deviation, no matter how the system pressure changes are to maintain the same set of flow, the valve of these functions make the network traffic regulation once completed, the network work becomes simple Of the flow distribution, effectively solve the network of hydraulic disorders.
