How should natural gas pneumatic ball valve be maintained? Natural gas pneumatic ball valve is used as a valve for natural gas transmission and control. Since natural gas contains sulfur and sulfur dioxide, which is highly corrosive, and natural gas has the particularity of flammability and explosion, there are many differences between the installation, use, and later maintenance of natural gas pneumatic ball valve and ordinary pneumatic ball valve. Only correct use and maintenance can ensure safety. 　　

Device of pneumatic butterfly valve:
