Product Description
The double eccentric segmented ball valve (also named semi ball valve) is designed with eccentric valve body, eccentric ball and valve seat, valve stem do automatic centering when doing the rotary motion in the common path , is getting tighter and tighter when the valve closing, thus fully meet the good sealing purpose. The valve ball and valve seat completely separate off and eliminate the abrasion of the sealing ring, and overcomes the traditional ball valve seat and ball sealing surface wear problem, the metal surface of the valve seat is well protected. This kind of segmented ball valve is especially  applied for the steel industry, aluminum industry, soda ash industry,for mediums like fiber, small solid particles, pulp, ash, oil and gas medium etc.

Applications of the double eccentric segmented ball valve: general valve, pipeline valve, slurry valve, gas valve, oil and chemical industry valve, pulverized coal ash spray valve, soda ash valve, several major series. Are the replacement products of gate valve, globe valve, Y-type valve, ball valve In the petroleum, chemical, metallurgy, electric power, gas and other industries are. At present, the valve has been popular in the steel industry of pulverized coal injection, alumina industry of pulp, the mother liquor and alumina powder transportation, electric power industry of hydraulic (or stem) ash, soda ash industry of carbonation tower, the mother I, II of mother, ammonia, ammonia II, soda ash, melamine. The gas industry and other working conditions.
