General Globe Valve (Single Disc)

The globe valve is mainly composed of valve body, valve cover, valve disc and valve stem. The handwheel applies a certain torque at the upper end of the valve stem. The valve stem is passed to the valve petals through the valve stem, so that it moves up and down along the valve stem axis to achieve fully turned on or fully closed movements. The force applied by the handwheel acts on the disc to hold it against the seat to seal. The single disc globe valve is designed to enter the medium by the valve disc sealing surface below, the medium force is opposite to the direction of valve closing, so the valve closing torque is large, so the single disc globe valve is mainly used in low pressure or small diameter pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.…

The globe valve is mainly composed of valve body, valve cover, valve disc and valve stem. The handwheel applies a certain torque at the upper end of the valve stem.

At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.
Features & Benefits

During the opening and closing process, the friction between the valve petals and the cover surface is small and wear-resistant. The itinerary height 

is relatively small. The action is sensitive and the sealing performance is good; The overall structure, simple and compact, beautiful shape. Long 

service life and high reliability.


General Information

Application Scenario: The deeper valve is generally used on the pipelines that are not strict with the flow resistance on the pipeline, that is, the place where the pressure loss is not large. For example, a high-temperature and high pressure working medium, toxic and harmful risk liquids require 

closure to ensure long-term sealing and leakage. Under normal circumstances, the requirements for use requirements are reliable. Such as the 

application of power industry, petroleum refining, petrochemical industry, marine oil, tap water engineering in urban construction, chemical industry 

and other fields.
