SD343H telescopic butterfly valve

One. Structure and characteristics

1. Novel and reasonable design, unique structure, light weight, convenient operation and quick opening and closing.

2. The telescopic butterfly valve can not only adjust and intercept the flow, compensate for the thermal expansion and contraction caused by the temperature difference of the pipeline, but also provide convenience for the installation, replacement and maintenance of the valve.

3. The sealing parts can be adjusted and replaced, and the sealing performance is reliable.

Two. Installation precautions

1. The SD343H telescopic butterfly valve must be laid flat before installation, and do not bump it at will.

2. The structural length of SD343H telescopic butterfly valve is the minimum length when it leaves the factory.

3. When the length of the pipeline exceeds the installation length of the expansion valve, please adjust the interval between the pipelines and do not force the expansion valve to avoid damage to the expansion valve.

4. SD343H telescopic butterfly valve can be installed in any position. When used for temperature compensation, after the pipeline is installed, brackets should be added along the two ends of the pipeline axis to prevent the telescopic valve telescopic tube from being pulled out.
