品牌：RETZ/我们一直致力于流体控制和测控领域的持续创新，始于2005……(黄铜)进口内螺纹平衡阀设计精密，结构简单，参数准确，流量大且测压孔位于同侧，测量方便，节能作用The (brass) imported internal thread balance valve is designed with precision, simple structure, accurate parameters, large flow rate, and the pressure measuring hole is located on the same side, making measurement convenient and energy-saving

进口内螺纹平衡阀技术参数 Technical paramete

(黄铜)内螺纹平衡阀具有开关截止功能，产品携带有测量接头，方便与测量设备的快速连接，当系统调试后可将锁定装置开启，方便日后可关闭静态阀进行管路维护与检修，结束后可以直接将阀门恢复到设定好的行程处，避免二次调试。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

内螺纹平衡阀安装前应确保系统内无杂物，请注意介质的流向与阀体上的流向标记一致，一般安装于系统的回水管，当与动态压差平衡阀配套使用时，安装于供水管。通常与弯头或水泵连接时，需要保持一定的直管段安装距离；当与弯头连接时，遵循阀前5d，阀后2d原则；当与水泵连接时，遵循10d原则
