(黃銅)內螺紋平衡閥具有開關截止功能，產品攜帶有測量接頭，方便與測量設備的快速連接，當系統調試后可將鎖定裝置開啟，方便日后可關閉靜態閥進行管路維護與檢修，結束后可以直接將閥門恢復到設定好的行程處，避免二次調試。The internal thread balance valve of the static balance valve has relevant cut-off functions. The product carries a measuring connector to facilitate the quick connection with the measuring equipment. After the system commissioning, the locking device can be opened to facilitate the closing of the static valve for pipeline maintenance and repair in the future. After the completion, the valve can be directly restored to the set maximum stroke to avoid secondary commissioning

內螺紋平衡閥安裝前應確保系統內無雜物，請注意介質的流向與閥體上的流向標記一致，一般安裝于系統的回水管，當與動態壓差平衡閥配套使用時，安裝于供水管。通常與彎頭或水泵連接時，需要保持一定的直管段安裝距離；當與彎頭連接時，遵循閥前5d，閥后2d原則；當與水泵連接時，遵循10d原則
