Ductile Iron 4 Inch Groove Type OS&Y Rising Stem Gate Valve


For a rising stem valve, the stem will go up while opening the valve and move down when you close the valve. You can see in the image. In inside screw design, the threaded portion of the stem is in contact with the flow medium and when you open the valve, handwheel rise with the stem. Whereas in the case of outside screw design, the only smooth portion is exposed to the flow medium and stem will rise above the handwheel. This type of valve is also known as OS & Y valve.  OS & Y means outside steam and York.
