Globe valve stem open to close distance is relatively short, stem and valve seat sealing surface perpendicular to the axis, which has a very excellent cut-off action, with little wear of on-off valve plate to seat sealing face. Globe valve is very suitable for cutting off or adjusting the media and throttle using. Flanged globe valves are bolted and flanged to the piping systems, can only be used in one direction.

1. The stroke of opening to closing is relatively short, Start-Stop time is short.
2. Valve has good sealing and long use time, the friction of sealing surface is small.
3. Globe valve seat and disc are easy to repair and can be replaced without removal from pipeline systems.
4. Medium impact on the valve plate is small, suitable for controlling medium flow.
Before installation, carefully check whether the performance of the globe valve meets the engineering needs, and conduct a pressure leakage tests. Note that the flow direction of the medium is consistent with the direction indicated by the arrow of the valve body.
Before installation, check whether the manual setting operation is flexible and there is no clamping phenomenon in the installation.

The stop valve operating mechanism should be about 1.2m from the ground when the stop valve is installed. For individual globe valves over 1.8m high and infrequently operated, sprockets, extension rods, movable platforms, and movable ladders are available.
For globe valves in horizontal pipelines, it is best to install the stem vertically upward rather than downwards. The installation position of the ground stop valve is inclined, and it will be inconvenient to operate and maintain.
For the stop valves installed side by side on the pipeline, there should be space for operation and maintenance, and the distance between the handwheels should not be less than 100mm; If the spacing is narrow, the valves should be staggered.
Choose suitable studs and gaskets according to the temperature, pressure, and medium.
