Special industrial butterfly valve is characterized by high temperature resistance, high applicable pressure range, large nominal diameter of valve, carbon steel valve body, and metal ring instead of rubber ring for sealing ring of valve plate. The large high-temperature butterfly valve is welded with steel plate and is mainly used for the flue and gas ducts of high-temperature media.

Advantages of stainless steel pneumatic butterfly valve
Stainless steel pneumatic butterfly valve is made of stainless steel corrugated pipe with one or more layers of steel wire or steel belt mesh sleeves, and both ends are equipped with connectors or flange heads. It is used to escort flexible elements of various media as various equipment signal lines, transmission wires and cables, and optical fiber and cable maintenance:
1) Wire maintenance tubes for armored optical cables, fine optical rulers, optical measuring instruments, medical instruments, machinery and equipment; 2) It is applicable to public telephones, remote water meters, door magnetic alarms and other equipment that need to stop safety protection for wires; 3) Maintenance of various small wires
4) It is used for network cable maintenance of various computers, robots, etc.
Advantages of stainless steel pneumatic butterfly valve:
1) Flexible or between pitches.
2) It has good scalability, no blocking and stiffness.
3) Light weight, good divergence of caliber.
4) Good flexibility, repeated bending and flexibility.
5) Good corrosion resistance and high temperature resistance.
6) Anti rat bite, good wear resistance, and avoid abrasion of internal wires.
7) It has strong bending resistance, tensile property and lateral pressure resistance.
8) Soft and smooth, easy to position the threading device.
