First, the national standard cut 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 the bottom of the valve into the valve, the operating force to overcome the resistance is the stem and packing friction and pressure generated by the pressure of the valve, close the valve force than the valve, so the stem Of the diameter to be large, otherwise there will be stem stem bending failure. In recent years, from the self-sealing valve appears, the flange stop valve medium flow will be changed from the top of the valve into the valve chamber, then under the action of the media pressure, the valve is small, and open the valve force, The diameter of the rod can be reduced accordingly. At the same time, in the role of the media, this form of stainless steel pneumatic valves are more stringent.
