Working Principle:
American standard principle of forged steel ball valve is rely on the screw type ball 90 degree Angle as a condition of opening and closing, when the valve core is an Angle of 90 degrees ball in a straight flow channel, small flow resistance, low friction factor, it is not easy to damage. Beautiful mark forged steel ball valve is especially suitable for application in sulfide environment make sulfide cracking, not easily be medium erosion, has been widely used in various industries.
Structure:
Forged steel ball valve body along the channel valve axis in two seat place in vertical section is divided into three parts, valve along the central axis left and right sides is symmetrical, the valve stem it in the line is mainly used for cutting, distribution, and change the flow direction of medium. Standard seat is spring structure, will seat into the ball, to ensure the sealing performance of good import and export. Stage I valve forged steel ball valve American standard with excellent performance, high reliability, wide range of USES, the price is reasonable, etc. Table I forged steel ball valve American standard in accordance with API standard. Is widely used in: chemical, oil, natural gas, metallurgy, and other industries and medium containing hydrogen sulfide, impurities, serious corrosion of long distance natural gas pipeline
