Description Material Performance Product Size Specifications

Q41F ball valve has a full size and necking of two structural forms. Even for post delivery, easy slagging medium pipeline ball valve full bore should be used, to facilitate regular paraffin blowing by sweeping device. For conveying gas or physical properties similar to the water in the medium of the pipe should be used to reduce the ball valve, because of its weight than the full diameter of 30% or so, is conducive to reducing the pipeline load, reduce costs. Ball valve is a rotating angle of 90 degrees rotation of the valve, the sealing performance is excellent, (full diameter ball valve) flow coefficient of large flow resistance coefficient is small, simple structure, long life, easy maintenance. Used to cut off or connect the line of medium, use different materials, can be separately applied to water, steam, oil, liquefied petroleum gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing medium, urea and other media.
