Closing perpendicular to the axis of the valve stem and the valve
seat sealing surface of the valve
Stem to open or close the relatively short trip, and has a very reliable cutting action makes this valve is suitable as a medium cut off or adjust the throttle.
Cut-off valve of the valve is in the open position, the valve seat and valve sealing surface is no longer between contact, and has a very reliable cutting action and combine this valve is suitable as a medium cut or regulation and section flow.angle seat valve
Once the valve is turned on, its seat and valve sealing surface is no longer in contact, so it's less mechanical wear of the sealing surface is relatively easy because most of the shut-off valve seat and valve repair or replacement the sealing element without remove the entire valve from the pipeline, and is very applicable for the valves and pipeline welding into one of the occasions. The direction of flow of the medium through such valves has changed, and therefore a higher flow resistance of the cutoff valve in the other valve.pneumatic accessory
