The O type shut -of ball valve is kind of quater-turn on -off vale .It is mainly used for shut-off contorl of media The ball valve of this series adopts round hole in the ball When opended It is diectly connected to the body flow channel. featured by high flow capacity.Compared With pluger valves.it has small structural sizes.light weight and the funcion 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.tempertaure and liquid level of all gases.liquids or corrosive gases and liquid media.
