发射器
Transmitter

　　可配置在所有高级电动阀门上。这种发射器模块通常与4-20mA定位器主板一起使用，并采用主板电源。也可以作为备用反馈发射器以备没有位置控制器时使用，但是作为备用装置时需要外部电源供应。这种内部安装模块直接提供4-20mA比例输出信号给定位器主板反馈电位计。这种信号可以被远程仪器用来监控或显示执行器的开关位置。零点和间距调整使得发射器的4-20mA信号调整能够与定位器主板的零点和间距位置保持一致。
　　Available for all Premium Electric actuated valves. The Transmitter module is normally used with the 4-20mA Positioner Board and the board's power supply. It can also be used as a stand alone feedback transmitter when no position controller is used, but will require an external power supply for stand alone application. This internally mounted module provides a 4-20mA output signal directly proportional to the Positioner Board feedback potentiometer. This signal can be used by a remote instrument to monitor or display actuator position. Zero and span adjustments allow adjustment of the Transmitter's 4-20mA signal to correspond with the zero and span positions set by the Positioner Board.

摩擦闸
Friction Brake

　　可配置在所有高级电动阀门上。这种内部安装装置用来消除执行器电击在循环终点出现的机械“惯性”。对于所有电动蝶阀，摩擦闸是标准配置，但是并不应用在隔膜阀上。
　　Available for all Premium Electric actuated valves. Internally mounted device which is used to eliminate mechanical "coast" of the actuator motor at the end of its cycle. Brakes are standard on all electrically actuated Butterfly Valves and not applicable to Diaphragm Valves.
