安装说明 Installation instructions

动态压差平衡阀可以单独使用，亦可与静态平衡阀配合使用。水流方向需与阀体箭头方向符合一致。安装之前应当冲洗管路，并建议在前端安装过滤器。毛细管应连接在供水管路的上方或水平处，但不可位于管路下方，以防被灰尘微粒堵塞，水系统打压测试之前，必须把毛细信号管安装连接好并且旋转阻断阀。否则压力过大会导致压差调节器的损坏 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.

动态压差平衡阀始终安装于回水管上，当与静态平衡阀配合使用时，如下图所示静态平衡阀安装与供水管  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
