BQ641F, BQ641Y pneumatic insulation ball valve and ball valve difference is bigger, we can distinguish from the function to go up and ball valve and different role BQ641F, BQ641Y pneumatic thermal insulation ball valve, from ball valve and insulation BQ641F, BQ641Y pneumatic ball valve structure up to distinguish. 【 Functional difference between 】 BQ641F/Y pneumatic of heat preservation for cold insulation ball valve has a good feature, and valve and pipe diameter is consistent, at the same time can effectively reduce the pipeline heat loss in the media. Is mainly used in petroleum, chemical, metallurgical, pharmaceutical, food and other kinds of systems, in order to transport under normal temperature solidification of high viscosity medium. Due to the integral structure and insulation ball valve what smaller than the average ball valve, lighter weight, and no leakage, sealed performance is good, the jacket more pressure than casting of solid carbon steel pipe welding is used. Ball valve and BQ641F, BQ641Y pneumatic insulation ball valve difference is bigger, ball valve, 球阀) Opening and closing is a sphere, driven by the valve stem, and for ball Industrial Valves axis rotate 90 & deg; Open or closed. Can also be used on regulation and control of fluid, mainly used for cutting in line, distribution, and change the flow direction of medium, good sealing, convenient operation, opening and closing fast, simple structure, small volume, small resistance, light weight, etc. 【 Physical difference between 】 【 BQ641F, BQ641Y pneumatic insulation ball valve ball valve Summary 】 BQ641F, BQ641Y pneumatic insulation ball valve and ball valve and the difference function, are quite different in application, in the selection of a certain need to pay special attention to diameter, pressure, material and use of media, no matter when the design, or in the purchase, must be in strict accordance with the relevant technical requirements.
The increasing consumption demand in key segments such as os&y gate valve, resilient seated valve and cast iron gate valve have been driving the sales of and its derivatives worldwide.
