1. What are the types of ball valves?
There are various types of ball valves, including pneumatic, manual, electric ball valves, fixed, floating, elastic ball valves, low temperature, high temperature, normal temperature ball valves, stainless steel, carbon steel, aluminum alloy, ceramic, plastic ball valves, etc. Among them, the floating ball valve will move the internal ball under the action of pressure to seal the outlet; On the other hand, the ball body does not move under the pressure of a fixed ball valve, but its seat can be moved to seal.
Second, how to choose a ball valve
1. There are various types of ball valves, and we should choose different types of products according to the installation and use of ball valves when choosing ball valves, for example, if we need to install ball valves on natural gas transmission pipelines, then we need to choose full-bore and welded products; If the ball valve is only used to regulate the flow of media in the pipeline, we can choose the pneumatic V-type opening to adjust the ball valve; If the pipeline is transmitting a cryogenic medium, when installing this type of pipeline ball valve, it is necessary to choose a cryogenic ball valve and so on.
2. When we choose a ball valve, we must first understand the caliber of the pipeline ball valve interface, and choose the size of the corresponding type of ball valve. Try to avoid the problem that the ball valve cannot be installed after purchase. When selecting a ball valve, we also need to consider the discharge, flow resistance and other related parameter information of the electric ball valve according to the actual situation of the pipeline.
3. The material of the ball valve is diverse, and we can consider the material of the ball valve according to the pipeline medium when purchasing, if the ball valve medium is water, we can use the ball valve made of plastic and cast iron. If the temperature of the pipeline medium is high, we can choose stainless steel ball valve and so on. When purchasing ball valves, we also have to look at the brand of the product, and we can consider buying ball valve products with strong strength and good reputation.
