I believe that the word "valve" is no stranger to friends who contact the fluid pipeline system, to put it in layman's terms, the valve belongs to the control element on the pipeline, and the main role of the valve is to isolate the equipment and pipeline system, regulate the flow, prevent backflow, regulate and discharge pressure, etc. The protagonist of today's introduction is one of the valves, which is the famous "all-welded ball valve", which can be used to transport media on pipelines such as petroleum, chemical, natural gas, pharmaceutical industry, food industry, etc. Since it is important to choose the most suitable valve for your own pipeline in the piping system, it is also important to understand the characteristics of the valve and the steps and basis for selecting the valve.
So what is an all-welded ball valve? All-welded ball valves
As the name suggests, the all-welded ball valve adopts the all-welded structure as a whole, so the all-welded ball valve will not leak, which greatly improves the service life of the valve can reach 10 years, because the valve seat is composed of Teflon sealing rings, it has a strong adaptability to changes in pressure and temperature, and there must be no leakage within the marked pressure and temperature range. The ball of the all-welded ball valve is made of 304 stainless steel, and the processing process of the ball is tracked and detected by an advanced computer detector, and the processing accuracy is high. Since we designed the valve body to be made of the same material as the pipe, there will be uneven stresses. The sealing ring body is made of PTFE with a content of 20% C (carbon), which strictly guarantees zero leakage.
