Globe valve refers to the valve that the plate moves along the center line of the valve seat. According to this form of the valve movement, the change of seat opening is proportional to the valve stroke. Because the opening or closing stroke of the stem is relatively short, and has a very reliable cutting function, it is very suitable for flow regulation. Globe valve can be divided into external thread type and internal thread type according to the thread. Globe valve can also be divided into straight type and angle type with the flow direction. Globe valve can also be divided into straight-flow type and angle type with the flow direction. Globe valve can be divided into packing sealing type and bellow sealing type according to the sealing form.
1. Simple structure, convenient manufacture and easy to maintenance
2. Small working stroke, short opening and closing time.
3. Good sealing, low friction between the sealing surfaces and long service life.
1. Big flow-resistance and large opening and closing power
2. It is not suitable for the medium with particle, viscosity and easy-coking.
3. Poor regulation performance
