The opening and closing parts of the high-pressure globe valve are plug shaped valves. The sealing surface is flat or conical. The valve moves in a straight line along the center line of the fluid.The movement of the stem is also in the form of a lifting rod (stem lift, handwheel lift), a lifting rotary rod (hand wheel and valve stem turn up and down together, the nut is set on the valve body).Globe valves are only suitable for full open and full closed, no regulation or throttling is allowed.

Since the high-pressure globe valve is a valve with a forced seal, pressure must be applied to the valve when the valve is closed to avoid leakage of the forced seal ridge.When the medium from the bottom of the valve into the valve, the operating force must overcome the resistance is the friction of the valve stem and filler high pressure globe valve pressure and the pressure of the medium produced thrust, because the force of the shutoff valve is greater than the force of the open valve, so the valve stem diameter is large, so it will also occur the fault of the stem top bend.

In recent years, since the appearance of the sealing valve, the medium flow of the globe valve from the upper part of the valve into the valve chamber, zhejiang hydraulic accumulator wholesale under the pressure of the medium at this time, the force of the shutoff valve is small, the force of opening the valve is large, the diameter of the valve can be reduced accordingly.At the same time, under the action of the medium, this type of valve is also relatively strict.China's valve "three into" has been regulated, ningbo hydraulic accumulator wholesale cut-off valve flow from the top down.
