SD341X-6, SD341X-10 flange type telescopic butterfly valve has the function of automatically compensating for the thermal expansion and contraction of the pipeline, and is suitable for loading and unloading at temperatures below 425 °C, nominal pressure below 1.6 MPa, chemical, electric power, papermaking, The best means of regulating flow and breaking fluid on industrial pipelines such as drainage and municipal construction.
1. Unique structure, flexible design, light weight, labor saving, rapid opening and closing
2. The telescopic butterfly valve not only compensates for the thermal expansion and contraction caused by the temperature difference of the pipeline, but also provides convenience for the installation and replacement of the maintenance valve.
3, the sealing part can be adjusted and replaced, the sealing performance is reliable
1. The telescopic butterfly valve must be laid flat before installation. Do not bump it at random. It is strictly forbidden to remove the bracket during operation.
2. The length of the telescopic butterfly valve is the minimum length when it leaves the factory. When it is installed, it is pulled to the installation length (ie the design length).
3. When the length between the pipes exceeds the installation length of the telescopic valve, please adjust the pipe spacing. Do not force the telescopic butterfly valve to avoid damage to the butterfly valve.
4. The telescopic butterfly valve can be installed at any time for temperature compensation. After the pipeline is installed, it is necessary to add brackets along the axial direction of the pipeline to prevent the telescopic valve from being pulled out.
