Products Name: Special Globe Valve for Liquefied Gas
LPG valves are forced to seal the valve, so the valve is closed, you must apply pressure 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 friction stem and packing 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.
