安裝示意圖 Installation diagram

安裝閥門前，必須清潔管道避免磨損。安裝閥門時，需要根據閥體上注明的流向安裝。必須避免管道力 作用在閥體上。同時，應避免閥門振動。（必須在閥門上游安裝過濾器）Before installing the valve, the pipeline must be cleaned to avoid abrasion. When installing the valve, it shall be installed according to the flow direction indicated on the valve body. Pipe forces must be avoided from acting on the valve body. At the same time, valve vibration shall be avoided. (filter must be installed upstream of the valve)
