Classification of globe valves

According to the channel direction, the globe valve can be divided into：

1. Straight-through globe valve

2. Direct flow globe valve: In direct flow or Y-shaped globe valve, the flow passage of the valve body is in a diagonal line with the main flow passage, so that the damage degree of the flow state is smaller than that of the conventional globe valve, so the pressure loss through the valve is correspondingly small.

3. Angle globe valve: In the angle globe valve, the fluid only needs to change its direction once, so that the pressure drop through this valve is smaller than that of the conventional structure of the globe valve.

4. Plunger type globe valve: This type of globe valve is a variation of the conventional globe valve. In this valve, the disc and valve seat are usually designed based on the plunger principle. The valve clack is polished so that the plunger and the valve stem are connected, and the sealing is achieved by two elastic sealing rings sleeved on the plunger. The two elastic sealing rings are separated by a collar, and the sealing ring around the plunger is pressed firmly by the load exerted on the bonnet by the bonnet nut. The elastic sealing ring can be replaced and can be made of various materials. The valve is mainly used for "open" or "close", but it is equipped with a special form of plunger or special collar, which can also be used to adjust the flow rate.
