What is the difference between hydraulic three-way and hydraulic four-way

There are obvious differences between hydraulic three-way and hydraulic four-way in hydraulic systems, mainly reflected in the following aspects:
Structure and function:
Hydraulic tee, also known as T-joint, is a simple and widely used joint in connecting pipelines. Its main function is to divert fluid from one pipe to two other pipes in hydraulic systems, and is usually used in situations where the flow rate is equal on branch pipelines.
Hydraulic four-way fittings, also known as four-way fittings or four-way joints, have four interfaces and are typically used to connect one inlet to three or more outlets. It is suitable for scenarios where one hydraulic component is connected to three hydraulic components separately, and is generally used for scenarios such as diversion and merging.
Usage scenario:
Hydraulic three is commonly used in scenarios where multiple hydraulic components are connected to each other, such as connecting hydraulic cylinders, oil pumps, and oil inlet ports.
Hydraulic four-way is more suitable for scenarios that require diversion or merging.
Alternative:
Although hydraulic four-way and hydraulic three-way can achieve similar connections in some cases, their usage scenarios and functions are different. Therefore, when designing and selecting hydraulic system pipelines, appropriate pipe fittings should be selected according to specific needs. It is not possible to simply replace a three-way with a four-way, unless there is a real need for special needs such as diversion or merging.
Appearance and dimensions:
The shape of the hydraulic tee is mainly T-shaped, with three interfaces. Its size specifications are diverse, including geometric dimensions (such as appearance dimensions, center height, angle, etc.) and interface dimensions (such as the connection interface of pipes and joints).
The hydraulic four-way valve has four interfaces, which can be of equal diameter (with the same size at the end of the connecting pipe) or of different diameter (with the main pipe having the same connecting pipe size, while the connecting pipe size of the branch pipe is smaller than the connecting pipe size of the main pipe).
Overall, there are differences between hydraulic three-way and hydraulic four-way in terms of structure, function, usage scenarios, and external dimensions. In hydraulic system design, suitable pipe fittings should be selected according to actual needs.
