The following cases, to go with locator: 1, medium pressure high pressure big time; 2, valve diameter is large Forged Gate, Globe, Check Valves (DN 00); 3, high or low temperature control valve; 4, the action necessary to raise the speed control valve; 5, using standard signal, the operation of non-standard spring when the implementing agency (20 ~ 100KPa spring outside the range); 6, when used for sub-process control; 7, when the valve to achieve the reverse action (air to close each open-type gas conversion); 8, need to change the valve's flow characteristic time (you can change the positioner cam); 9, no spring actuator or piston actuator, the proportion of action to achieve the time; 10, electrical signals to operate pneumatic actuator must Distribution - gas valve positioner.

下列情况下，要配定位器： 1、介质压力高、压差大的时候； 2、调节阀口径大时（DN00）； 3、高温或低温调节阀； 4、需要提高调节阀的动作速度时； 5、用标准信号、操作气动管路截止阀非标准弹簧的执行机构时（20～100KPa以外的弹簧范围）； 6、用于分程控制时； 7、使阀门实现反向动作时（气关式和气开式互相转换）； 8、需要改变阀的流量特性时； 9、无弹簧执行机构或活塞执行机构，要实现比例动作时； 10、用电信号去操作气动执行机构时，必须配电-气阀门定位器。

下面所开列情况下，要配定位器：一、介质压力高、压差大的时辰； 2、调节阀口径大时（DN00）； 3、高温或低温调节阀； 4、需要提高调节阀的动作速度时； 5、用标准旌旗灯号、操作气动管路截止阀非标准弹簧的执行机构时（20～100KPa以外的弹簧范围）； 6、用于分程节制时；七、使阀门实现逆向动作时（气关式和气开式互相转换）； 8、需要改变阀的流量特性时；九、无弹簧执行机构或活塞执行机构，要实现比例动作时； 10、用电旌旗灯号去操作气动执行机构时，必须配电-气阀门定位器。

Found filling pressure cap low, should be added fillers, such as found in the dry filler PTFE B sclerosis, should be promptly replaced; should pay attention to the inspection tour of the operation of control valve, check valve position indicator and regulator output is anastomosis; on the control valve with positioner should always check gas source, identify problems in time processing; should be kept sanitary control valve as well as parts are ready.

如发现填料压帽压得很低，则应补充填料，如发现聚四氟乙燥填料硬化，则应及时更换；应在巡回检查中注意调节阀的运行情况，检查阀位指示器和调节器输出是否吻合；对有定位器的调节阀要经常检查气源，发现问题及时处理；应经常保持调节阀的卫生以及各部件完整好用。
