First, the national standard globe  valve introduction

GB   globe  valve is a mandatory sealed valve, so the valve is closed, the   pressure must be applied to the valve to force the sealing surface does   not leak. When the medium from below the valve into the valve, the   operating force needed to overcome the resistance is the valve stem and   packing friction and the thrust generated by the media pressure, off the   valve force than the valve open, so the valve stem The diameter should   be larger, otherwise it will happen valve stem bend. In recent years,   from the self-sealing valve appears, the flange of the media cut off the   valve to change from the top of the valve into the valve chamber, then   under medium pressure, the valve closing force is small, and open the   valve force, valve The diameter of the rod can be reduced   accordingly. At the same time, in the medium, this form of stainless   steel pneumatic valve is also more stringent.
