ROTORK YT-1000RDN532S00是一种从控制器或控制系统中接收4~20mA直流电流信号，并向直行程气动执行机构输送空气来控制阀门开度的装置。

结构特点：

在5~200Hz范围内无共振现象。

正作用和反作用，单作用和双作用之间可方便转换。

对于小型执行机构产生的振动，可通过添加定位器的节流孔来解决。

空气消耗量少，经济性好。

不用更换零件就可以实现1/2范围内的分程控制。

Structural features:

There is no resonance phenomenon in the range of 5~200Hz.

It is easy to switch between direct acting and reverse acting, single acting and double acting.

For the vibration generated by small actuators, it can be solved by adding the orifice of the positioner.

Low air consumption and good economy.

Split-range control within 1/2 range can be achieved without replacing parts.
