Globe Valve/ Globe Valve
Globe valve, also known as hot steam valve, stop valve, or bellows seal valve, the English name is Globe Valve.
As the name suggests, the valve (globe valve) has a spherical internal structure design, divided into 2 parts including the upper half and the lower half separated by a partition with a circular hole where the lip is located. Substance can flow through when the valve is open. The valve disc is tapered in shape, directly connected to the valve stem and directly connected to the rotating handle located on the valve stem to open and close and regulate the flow inside the system.
Another point worth considering in this type of valve is that the pressure loss in a globe valve will be much larger than in other types of valves, because the flow design through the valve is S-shaped, and the operating time of the valve therefore also increases because the design of the globe valve is to operate by rotating 360 degrees and the valve must rotate a few times to be able to close or open the entire valve stroke, with the design of the globe valve. is to be able to open and close the flow slowly and proportionally. So globe valves are often used in systems such as: Hot steam, hot oil, hot water, etc. Because when the system is being used at high pressure, suddenly opening and closing the valve can lead to pressure shock, affecting the equipment inside the valve or the devices attached to the front.
