Pneumatic ball valve of the commonly used accessories how to choose?

in the previous article, we introduced the commonly used pneumatic ball valve accessories for everyone, today we mainly talk about specific how to choose the commonly used accessories. Pneumatic ball valve at the time of installation in order to meet the different needs of different pipe type of pipeline system, the need to choose the specification of different attachments, also known as pneumatic components, such as pneumatic head type, electromagnetic valve, filter, pressure reducing valve as well as the limit switch and so on, the following is to choose the various pneumatic components, attachment need to pay attention to place:, selection of pneumatic head. When selecting a pneumatic head, the first is to make sure is to use a single acting pneumatic head or use double-acting pneumatic head, then I can according to the application environment, the air source pressure valve etc parameters to choose the output torque of pneumatic head. , solenoid valve, the choice of the main consideration scope of the pressure, flow medium, flow coefficient, working temperature, explosion-proof requirements as well as voltage and so on whether to meet the needs of the pneumatic valve. , filtering pressure reducing valve need to pay attention to the choice of the main pressure range, working temperature, the circulation medium, the filter accuracy as well as the drainage device, etc. , selection of limit switch. Have to choose the color of need limit switch position indicator meets the requirements, feedback method is inductive or mechanical and their level of explosion-proof whether meet the requirements, and so on. Above is the pneumatic ball valve when choosing the pneumatic components, such as common attachment matters needing attention.
