The movable cutter head designed for mass machining of pneumatic ball valve shell not only ensures machining accuracy (concentricity), but also facilitates assembly and disassembly (assembly and disassembly time only takes more than 20 seconds). By compensating the error of the arc radius of the tool tip, the accuracy of adding soil on the radius of the arc surface is effectively guaranteed. This machining method is suitable for machining the inner surface of most pneumatic ball valve shells with disassembly holes.

Instructions for purchase of plastic coated pneumatic butterfly valve
For the transmission lines of many equipment, good safety precautions must be stopped to better ensure the normal transmission of the entire internal line. This requires the use of maintenance equipment such as plastic coated pneumatic butterfly valves to better ensure the good operation of the internal transmission lines, As for the purchase of this product, people should carefully understand and control some of its features, so as to better ensure the application effect.
For the purchase of plastic coated pneumatic butterfly valve, people should carefully understand the size of the hose, that is, the internal diameter of the whole hose and the size of the two connectors, so as to ensure that there will be no more problems in the use process. For the use of the hose, as long as the size and specification are accurate, In this way, the perfect fitting after the device can be better guaranteed, and the application effect can be guaranteed. If the fitting is very tight, it can also ensure that there will be no leakage.
Therefore, when purchasing the plastic coated pneumatic butterfly valve, we should understand the characteristics of the product and its application effect. The most important thing is to strictly control its specifications, so as to ensure the improvement of application effect.
