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。
