[0002] Multi-way reversing valves are usually used to control the flow direction of fluids between different pipelines to achieve fluid diversion, confluence or switching functions. This type of valve usually has a valve body with multiple channels and valve cores inside. The connection or isolation between different channels is achieved by rotating the valve core or moving the position of the valve core.
