Pneumatic butterfly valve, as a component used to control pipeline flow and make and break, has been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower and so on. Among the known pneumatic butterfly valve technologies, the sealing forms of pneumatic butterfly valves include soft sealing and hard sealing. The sealing materials of soft sealing surfaces are mostly rubber, polytetrafluoroethylene, etc., while the hard sealing materials are mostly various alloys and metal materials. Metal sealed valves generally have longer service life than elastic sealed valves, but it is difficult to achieve complete sealing.

Take the pneumatic ball valve as an example. The reason why it is selected as the main product is mainly because of its considerable development prospects, which are specifically reflected in the following three aspects:
In terms of operation capacity, the pneumatic ball valve operates by means of the operation of the air supply valve handle and the adjustment of the regulating valve. As for the speed range, the products provided have multiple levels of choices, that is, under the same output power, compared with some other electric tools, they are significantly lighter and more suitable for long-term operation, You don't need to worry about its heating. Even if the compressed air engine is overloaded, as long as the starting tool just stops rotating, it can resume normal operation after the overload is removed.
