安裝說明 Installation instructions

動態壓差平衡閥可以單獨使用，亦可與靜態平衡閥配合使用。水流方向需與閥體箭頭方向符合一致。安裝之前應當沖洗管路，并建議在前端安裝過濾器。毛細管應連接在供水管路的上方或水平處，但不可位于管路下方，以防被灰塵微粒堵塞，水系統打壓測試之前，必須把毛細信號管安裝連接好并且旋轉阻斷閥。否則壓力過大會導致壓差調節器的損壞 RETZ internal thread dynamic differential pressure balancing valve can be used alone or in combination with static balancing valve. The water flow direction shall be consistent with the arrow direction of the valve body. The pipeline should be flushed before installation, and it is recommended to install a filter at the front end. The capillary shall be connected above or at the level of the water supply pipeline, but not below the pipeline to prevent it from being blocked by dust particles. Before the pressure test of the water system, the capillary signal pipe must be installed and connected and the blocking valve must be rotated. Otherwise, excessive pressure will cause damage to the differential pressure regulator.

動態壓差平衡閥始終安裝于回水管上，當與靜態平衡閥配合使用時，如下圖所示靜態平衡閥安裝與供水管  RETZ dynamic differential pressure balance valve is always installed on the return pipe. When used with the static balance valve, the static balance valve is installed on the water supply pipe as shown in the following figure
