Product Introduction：

High pressure globe valves belong to forced sealing valves. When the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve from below the valve disc, the operation needs to overcome resistance, which is the frictional force between the valve stem and packing and the pushing force generated by the pressure of the medium. The force required to close the valve is greater than that required to open the valve, so the diameter of the valve stem must be larger, otherwise the valve stem may bend due to pressure. The opening and closing component of a globe valve is a plug shaped valve disc, with a flat or conical sealing surface. The valve disc moves linearly along the centerline of the fluid. Globe valves are only suitable for fully open and fully closed, and are not allowed to be adjusted or throttled. The advantages are simple structure, small working stroke, and good sealing performance.
End connections comply with API Spec 6A specifications。
The working medium is unidirectional flow。
