globe valveThe axis of the valve stem is perpendicular to the sealing surface of the valve seat. The valve stem has a relatively short opening or closing stroke and a very reliable cutting action, making it very suitable for use as a medium for cutting, adjusting, and throttling.

Once the valve disc of the globe valve is in the open position, there is no longer contact between its valve seat and the sealing surface of the valve disc, and it has a very reliable cutting action. Therefore, this type of valve is very suitable for cutting off, regulating, and throttling media. This type of valve should generally be installed horizontally in pipelines.

Once the globe valve is in the open state, there is no longer contact between its valve seat and valve disc sealing surface, so its sealing surface has less mechanical wear. As most globe valves have valve seats and discs that are relatively easy to repair or replace, there is no need to remove the entire valve from the pipeline when replacing sealing components. This is very suitable for situations where the valve and pipeline are welded together. When the medium passes through this type of valve, the flow direction changes, so the flow resistance of the shut-off valve is higher than that of other valves.

Globe valve, also known as shut-off valve, is the most widely used type of valve. Its popularity is due to the low friction between the sealing surfaces during the opening and closing process, its durability, small opening height, easy manufacturing, and convenient maintenance. It is not only suitable for medium and low pressure, but also for high pressure.

The closing principle of a globe valve is to rely on the pressure of the valve stem to tightly adhere the sealing surface of the valve disc to the sealing surface of the valve seat, preventing the flow of the medium.

The shut-off valve only allows one-way flow of the medium and has directionality during installation. The structural length of the globe valve is greater than that of the gate valve, and the fluid resistance is high. During long-term operation, the sealing reliability is not strong.
