Manual stop valve stem axis and seat sealing surface perpendicular. Stem opening or closing stroke is relatively short, and has a very reliable cut off action, making this valve is very suitable as a medium cut off or adjust and throttle. This type of valve in the pipeline should be generally horizontal installation. Once the valve of the manual shut-off valve is open, its contact between the valve seat and the valve sealing surface no longer contacts and has a very reliable shut-off action, which makes it suitable for the shut-off or adjustment of the medium and Throttle use. Once the stop valve is open, its valve seat and disc seal surface no longer have contact between, and therefore its sealing surface mechanical wear and tear less, as most of the valve seat and the disc valve is relatively easy to repair or replacement Sealing components without having to remove the entire valve from the pipeline, which for the valve and pipe welding is integrated into the case is very applicable. The flow direction of the medium as it passes through such a valve changes, so the shut-off valve has a higher flow resistance than the other valves. More keyword search: Globe valve
