Pressure Seal Globe Valve 1500lb Socket Welding

Pressure Seal Globe Valve rotates the handwheel to raise and lower the valve stem and drive the valve disc to make a linear displacement parallel to the flow direction of the medium, so as to achieve the purpose of opening and closing. When the hand wheel rotates clockwise, the working medium enters from the channel below the valve clack. At this time, the applied sealing force must be equal to or greater than the sum of the required specific pressure and the upward force of the medium generated on the sealing surface.
When Pressure Seal Globe Valve is opened, when the opening height of the valve clack is 25%~30% of the nominal diameter, the flow has reached the maximum, indicating that the valve has reached the full open position. Therefore, the full open position of the stop valve shall be determined by the stroke of the valve disc.
