The methods for distinguishing the inlet and outlet of a ball valve are as follows:
Labeling: The inlet is usually marked "IN," and the outlet is marked "OUT." This is an important basis for differentiation.
Pipe Connection: During pipeline installation, the inlet is connected to the supply pipeline, and the outlet is connected to the equipment in use. This ensures that the pipeline system can operate normally according to the intended flow direction.
Cavity Size: From the valve's structural characteristics, the inlet is often connected to a larger cavity, while the outlet is connected to a smaller cavity. This design helps to better control fluid flow and improve valve performance.
Fluid Flow Direction: For experienced users, the inlet and outlet can be determined by the fluid flow direction. Typically, the inlet is connected to the upstream pipeline, and the outlet is connected to the downstream pipeline.
