The first pneumatic three-way welded flange ball valve and ball valve are suitable for PN1.0 connection to 4.0MPa. A valve in which the valve flap of a pneumatic check valve slides along the center line of the valve body. In-line check valve is a new type of valve. It is small in size, light in weight, and good in processing technology. It is one of the development directions of check valves. But the fluid resistance coefficient is slightly larger than that of the swing check valve. Swing check valves can also be used to supply pipelines for auxiliary systems whose pressure may rise above the system pressure. The high temperature check valve is a kind of automatic valve, the main function is to prevent the medium from flowing back, prevent the pump and the drive motor from reversing, and to discharge the container medium.
Second. It is suitable for many different media such as water, steam, oil, acetic acid, oxidizing and medium, urea. And can be used in many industries, such as: petrochemical, chemical, metallurgy, electric power, environmental protection, petroleum, light industry, etc.
Third. The working temperature range is relatively wide, generally between -29 to 180 degrees Celsius (the sealing ring is made of polytetrafluoroethylene) or -29 to 300 degrees Celsius (the sealing ring is para-polystyrene). On the road, it is used to cut off or connect the medium in the system pipeline.
Connected into a whole, three-stage and two-stage fourth air pressure 3 welded flanged ball valves and ball valves. The sports land adopts advanced technology imported from Taiwan, with reasonable structure and beautiful appearance. Elastic sealing structure, reliable sealing, easy opening and closing of the seat. The valve stem seal is inverted structure, and the valve stem does not come out when the pressure chamber is abnormal. The switch can be set with a 90° positioning mechanism, which can be locked as required to prevent misoperation.
Therefore, the advantages of the three-piece pneumatic flange ball valve are very important and prominent, so we need to have a very good choice in production.
