Classification of stop valves

:Kiss: The commonly used globe valves include the following types: 1) Straight-through globe valve; 2) Angle-type globe valve. In angle-type or Y-type globe valves, the flow channel of the valve body is at an angle to the main flow direction, which results in less disruption of the flow pattern compared to conventional globe valves, and thus the pressure loss across the valve is also lower. 3) Angle-type globe valve: In an angle-type globe valve, the fluid only needs to change direction once, resulting in a lower pressure drop across this valve compared to globe valves with conventional designs. 4) Plunger-type globe valve: This type of globe valve is a variant of the conventional globe valve. In this valve, the valve disc and seat are typically designed based on the plunger principle. The valve disc is polished to form a plunger that connects with the valve stem, and sealing is achieved by two elastic sealing rings fitted over the plunger. The two elastic sealing rings are separated by a collar, and the sealing rings surrounding the plunger are pressed in place by the load applied to the valve cover by the valve cover nut. The elastic sealing ring can be replaced and is made from a variety of materials. This valve is primarily used for opening or closing, but it also features a special type of plunger or special rings that allow it to be used for regulating flow.
