Product use: SD34lX flange type telescopic butterfly valve has the function of automatically compensating the thermal expansion and cold contraction of the pipeline, which is convenient for loading and unloading. It is used as the best device to adjust the flow and load and cut off the fluid in the industrial pipelines with the temperature below 425 ℃ and the nominal pressure below 1.6Mpa, such as petroleum, chemical, electric power, papermaking, water supply and drainage, municipal construction, etc.

Product use:
SD34lX flange type telescopic butterfly valve has the function of automatically compensating the thermal expansion and cold contraction of the pipeline, which is convenient for loading and unloading. It is used as the best device to adjust the flow and load and cut off the fluid in the industrial pipelines with the temperature below 425 ℃ and the nominal pressure below 1.6Mpa, such as petroleum, chemical, electric power, papermaking, water supply and drainage, municipal construction, etc.
Valve model:
The common models of flange type telescopic butterfly valve are: SD341X, SD341X-6, SD341X-10, SD341X-16, SD641X, SD641X-10P, SD941X, SD341F, SDS641F, SD341H, SD641H, SD941H, etc.
Product features:
1. Unique structure, flexible design, light weight, labor saving, quick opening and closing.
2. The telescopic butterfly valve can not only compensate the thermal expansion and cold contraction caused by the temperature difference shrinkage of the pipeline, but also provide convenience for the installation and replacement of the maintenance valve.
3. The sealing part can be adjusted and replaced, and the sealing performance is reliable.

Installation precautions:
Before installation, the telescopic butterfly valve must be placed flat, do not bump at will, and do not remove the support during operation.
When the telescopic butterfly valve leaves the factory, the structure length is the minimum length. When it is installed, it is pulled to the installation length (i.e. the design length).
When the length between pipes exceeds the installation length of expansion valve, please adjust the pipe spacing. Do not stretch and shrink the butterfly valve forcibly to avoid damaging the butterfly valve.
The telescopic butterfly valve can be installed at any time. When it is used for temperature compensation, after the pipeline is installed, supports should be added at both ends along the pipeline axis to prevent the telescopic pipe of the telescopic valve from pulling out.
