The disassembly of pneumatic ball valve requires patience, professionalism and what is required for disassembly. Therefore, the disassembly is not single. After disassembly, it must be installed. After disassembly, better equipment is the central location. We often meet many customers who call to say that they can't install the valve after disassembling it. More often, they can install the valve but the valve can't be opened or the action is slow. Why do some valves turn over after installation and the action is smooth, while some valves move slowly or do not act at all? Equipment is very important.

If the temperature indicated by the temperature pointer is less than or equal to 150 ℃, tetrafluoro sealing material is required. If the temperature indicated by the temperature pointer is higher than 150 ℃, hard sealing material is required. The pressure pointer corresponds to the material of the main body of the pneumatic butterfly valve. If the pressure value is smaller than 16 kg, the main body of the valve needs to be made of cast iron, and the temperature in the north is lower, Cast iron or cast steel valves need to be considered, but the cast iron material is relatively fragile. If the local temperature is very low, the valve surface is easy to crack. When the external pressure exceeds 16 kg, cast steel valves need to be considered. When purchasing valves, consumers need to comprehensively consider the above factors and select valves of corresponding materials to avoid accidents during the use of valves.
