Ce ANSI/API 607 API 6D High Performance O Type Ball Valve

The O type shut-off ball valve is a kind of quarter-turn on-off valve. It is mainly used for shut-off control of media. The ball valve of this series adopts round hole in the ball. When opened, it is directly connected to the body flow channel, featured by high flow capacity. Compared with plunger valves, it has small structural sizes, light weight and the function of self-cleaning between plug and seat. Therefore, it is very suitable for viscous, fibrous media and those containing suspended solid particles. With low heat expansion impact due to temperature, and good sealing performance, it is widely applied in the systems of such industries as petrochemical industry, metallurgy, chemical fiber, pulp & paper, medicine, hydroelectric station, etc. to meet the needs of remote control of process parameters such as flow, pressure, temperature and liquid level of all gases, liquids or corrosive gases and liquid media.body main technical parmanetersbody typetwo-piece,three-pieceNominal diameterDN15~500(NPS1/2~24)Nominal pressurePN 1.6~4.0Mpa(Clsaa150~600)Type of connectionflangedMaterialA216-WCB, A351-CF8, A351-CF8M, A351-CF3,
