(流量控制阀)静态平衡阀可代替截止阀关断功能，产品携带有测量接头，方便与测量设备的快速连接，节省调试时间，具有行程锁定功能，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RETZ The static balance valve can replacethe shut-off function of the stop valve. The product carries a measuringconnector, which is convenient for quick connection with the measuringequipment, saves debugging time, and has the maximum stroke locking function.When the system is commissioned, the locking device can be opened, which isconvenient for closing the static valve for pipeline maintenance and repair inthe future. After the completion, the valve can be directly restored to the setmaximum stroke to avoid secondary debugging.

静态平衡阀在开度≥50%时，误差不得大于±5%；10%≤开度≤50%时，误差不得大于±10%。故在产品选型时，建议设计流量下阀门开度大于50%为宜，同时为保证现场调试余量，阀门尽量设置在75%开度左右 RETZWhen the opening of static balance valve is ≥ 50%, the error shall not be greater than ± 5%; When 10% ≤ opening ≤ 50%, the error shall not be greater than ± 10%. Therefore, during product selection, it is suggested that thevalve opening should be greater than 50% under the design flow. Meanwhile, inorder to ensure the on-site commissioning margin, the valve should be set atabout 75% opening as far as possible.
