Manual globe valve is very suitable for medium cut off or regulation and throttling. The axis of the valve stem is perpendicular to the sealing surface of the valve seat. Generally, manual globe valves are installed horizontally. The opening or closing stroke of the valve stem is relatively short, and it has a very reliable shut-off action, which makes this valve very suitable for medium shut-off or regulation and throttling.
Once the globe valve is in the open state, there is no longer any contact between its seat and the sealing surface of the disc, so the mechanical wear of its sealing surface is small, because the seat and disc of most globe valves are relatively easy to repair or replace. It is not necessary to disassemble the whole valve from the pipeline when sealing the element, which is very suitable for the occasion where the valve and pipeline are welded into one. The flow direction of the medium changes when passing through this type of valve, so the flow resistance of the globe valve is higher than that of other valves.
Once the valve disc of the manual globe valve is in the open state, the contact between its valve seat and the sealing surface of the valve disc is no longer in contact, and it has a very reliable cut-off action. Throttling usage.
The above is a brief introduction of some related contents and working principles of the manual globe valve shared with you today. Do you understand the horizontally installed manual globe valve?
