The structure of the stop valve

Aug 18, 2020

The structure of the stop valve:   

The structure of the globe valve body includes straight-through, direct-flow and right-angle. Straight-through is the most common structure, but its fluid resistance is the greatest. Direct flow fluid has low resistance and is mostly used for fluids containing solid particles or high viscosity. Right-angle valve bodies are mostly forged, which is suitable for stop valves with smaller passages and higher pressure.



The installation and maintenance of the globe valve should pay attention to the following matters:   

1. The stop valve operated by hand wheel and handle can be installed at any position of the pipeline. 2. Handwheels, handles and dynamic mechanisms are not allowed for lifting. 3. The flow direction of the medium should be consistent with the arrow direction shown on the valve body.    


The shut-off valve has simple structure, convenient manufacture and maintenance, small working stroke, short opening and closing time, good sealing performance, small friction between the sealing surfaces, and long life.
