Globe Valve
The structure of globe valve is simpler than that of gate valve, and both its manufacturing and maintenance are relatively convenient.
The seal surface is not easy to wear and gall and has sound sealing performance. When being opened and closed, there is no relative slip between the valve flap and the seal surface of the valve, thus both the wear and gall are not severe and it has sound sealing performance and long service life.
When being opened and closed, the travel distance of the valve flap is small, thus the height is smaller than that of gate valve while the structure length is longer than that of gate valve.
When being opened and closed, the force torsion is large and it is laborious to open and close, and the time of opening and closing is relatively long. The fluid resistance is big because the medium channel in the valve is relatively tortuous. The fluid resistance and the power consumption are big.
When the nominal pressure of the medium flow direction PN ≦ 16MPa, downstream flowing is usually adopted and the medium flows upward from downward direction of the valve flap; when the nominal pressure PN ≧ 20 MPa, upstream flowing is usually adopted, and the medium flows downward from the upper direction of the valve flap. When being used, the globe valve medium could only flow in a single direction and the flow direction could not be changed.
The globe valve stem axis of the valve is perpendicular to the seal surface of valve seat. The opening or closing travel distance of the valve stem is relatively short and also it has the very reliable turning off action which enables this kind of value to be suitable for turning off the medium or functioning as adjustment and throttling.
