Q347 fixed worm ball two and three segments and fixed ball valve arranged at the side of the split valve section with the valve body along the axis perpendicular to the channel is divided into halves asymmetry, which in the pipeline is mainly used for cutting, distribution and change the media flow. Its pivot structure ensures accurate ball position. Standard seat with a spring structure, the seat to the ball, to ensure a good low pressure sealing performance. Before the ball valve, valve seat can be sealed, that is, the so-called two-way sealing characteristics, the use of self discharge valve, the chamber can be discharged outside the chamber. The pivot adopts the anti blow out protection structure, and the low friction coefficient of the bearing and the like. The company has excellent performance, high reliability, wide application, reasonable price advantages, suitable for chemical, petroleum, natural gas, metallurgy and other industries and natural gas containing hydrogen sulfide medium, impurities and corrosion of long distance pipe.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, caliber. Specific please contact or online advisory contact.
