Telescopic Butterfly Valve

The telescopic butterfly valve produced by Dazhong Valve Group is widely used in the drainage and gas pipeline systems of food, medicine, petroleum, chemical industry, light textile, papermaking, metallurgy, electric power, municipal and other industries. For connecting medium. The butterfly valve and the expansion joint are combined into one, the design is novel and reasonable, and the extension part is sealed with rubber.

• The butterfly valve is widely used in the drainage and gas pipeline systems of food, medicine, petroleum, chemical industry, textile, papermaking, metallurgy, electric power, municipal and other industries. .

• The valve is installed with the limit expansion joint. It can be axially expanded and contracted within a certain range to facilitate pipeline connection. It can also overcome the offset caused by the different axes of the pipeline butt, and has the ability to compensate the thermal expansion and contraction of the pipeline. function to ensure the safety of the pipe network system.

• The butterfly valve and the expansion joint are combined into one, the design is novel and reasonable, the structure is unique, the overall size is small, and the weight is light.

• Light and labor-saving operation, small flow resistance, reliable sealing, long service life, easy adjustment, easy on-site disassembly and installation.

• The stretched part is sealed with rubber, which can prevent leakage by adjusting the amount of compression, and the sealing performance is reliable.

• The limit screw is used to prevent exceeding the maximum expansion and contraction and ensure safe use.
