Globe valve is a forced-sealed valve, so the valve is closed, the pressure must be applied to the valve flap 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. According to the connection is divided into three kinds: flange connection, threaded connection, welding connection.When the globe valve is opened, the flap opening height is 25% ~ 30% of the nominal diameter, the flow rate has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the full-stop position of the valve, valve stroke should be determined.
