American standard flanged ball valves are designed and manufactured by API 600 and API 602, which are mainly used for cutting, distributing and changing the flow direction of media in pipelines. Q41F standard flange ball valve integral silica sol precision casting valve body, valve body surface fine, beautiful, no need to be polished. Design has anti-static, fire-proof structure, body parts, such as the selection of high quality stainless steel and the acid pickling and passivation, check and test do not contain any oil with pure water high pressure seal test, after the special craft processing, this kind of ball valve not only operating fast trot, small flow resistance, safe and reliable, and long service life (small seal flush). How it works: the American standard flanged ball valve works by rotating the valve to open or close the valve. Ball valve switch is light, small in size, can be made into a large aperture, reliable seal, simple in structure, easy to maintain, sealing surface and sphere are often closed, not easy to be eroded by media, and it has been widely used in various industries. Main application: American standard flanged ball valves are made of polytetrafluoroethylene, p-position polybenzene and other polymer materials. Because the material is soft, but to achieve a certain ratio of sealing pressure, is bound to increase the opening and closing torque. Suitable for water, steam, oil, nitric acid, acetic acid, oxidizing media, urea and other media. This product can be widely used in the control system of papermaking, petrochemical, chemical, metallurgy, electric power, environmental protection, petroleum, light industry and other industrial sectors.
