      Pneumatic Ball Valve: 5 Connection Methods

      In order to adapt to the needs of industrial automation development, pneumatic valve developed a lot of kinds, so there are many kinds of pneumatic ball valve connection, today we will talk about the most commonly used several kinds of connection, know what is the difference between their work scene.

      Flange connection is the two pipelines, pipe fittings or equipment, each fixed in a flange, and then between the two flanges plus flange gasket, and finally bolted to the two flanges tighten the two flanges to make it tightly combined with a removable joint. The main feature of the flange connection pneumatic ball valve is that it is easier to install and disassemble. However, it is bulkier than the threaded connection ball valve, and the corresponding price is higher. It is suitable for pipeline connections of various through diameters and pressures. However, when the temperature exceeds 350 degrees, bolts, gaskets and flanges become slack, will also significantly reduce the load on the bolts, the flange connection of a large force may produce leakage.

      Threaded connection is usually the valve in and out of the end of the processing into a conical pipe or straight pipe thread, can make its connection to the conical pipe threaded fittings or pipeline, is a simple and economical way of connection, commonly used in small pneumatic ball valves. The valve body is processed in accordance with the thread standard, there are two kinds of internal and external threads, corresponding to the threads on the pipeline, easy to install, suitable for some smaller flow rate application scenarios.

      Tri-Clamp connection only requires two bolts to complete the connection, is a fast and easy to dismantle the connection, suitable for low pressure valves, such as sanitary valves.

      Wafer type connection is a simple and reliable installation method. The valve is mounted in the middle of two flanges, and the valve and the two ends of the pipe are clamped together directly by bolts, realizing a fast and solid connection. The valve body usually has positioning holes for easy installation and positioning.

      Welded Pneumatic ball valves

      Welded connection is a firm and reliable connection, suitable for scenes with high requirements for connection strength and sealing, more reliable than flange connection. Both ends of the valve body are processed in accordance with butt-welding welding requirements, corresponding to the welding bevel of the pipe, and fixed on the pipe by welding. However, it is more difficult to disassemble and reinstall the valve with welded connection, so its use is limited to the occasions where it can usually operate reliably for a long time or where the usage conditions are loaded and the temperature is high. Such as thermal power stations, nuclear energy projects on the pipeline.

      總結

      In the selection of pneumatic ball valve connection, need to be based on specific engineering requirements, pressure levels and media characteristics to a reasonable choice, to ensure that the connection meets the actual needs of the project, to improve the service life and safety of the valve.

      As a valve manufacturer, DELCO has been specializing in the production of pneumatic ball valves for more than 20 years. DELCO’s pneumatic ball valves are used to remotely, quickly and safely control the flow of media.
