XSTOU DFS160-SR06-M, DFS160-SR07-M, DFS160-SR08-M, DFS160-SR09-M, DFS160-SR10-M pneumatic actuator uses pneumatic pressure to drive the actuator to open and close or adjust the valve, also known as pneumatic actuator Mechanism or pneumatic device, but commonly known as pneumatic head. Sometimes it is also equipped with certain auxiliary devices. Commonly used are valve positioners and handwheel mechanisms. The function of the valve positioner is to use the feedback principle to improve the performance of the actuator, so that the actuator can achieve accurate positioning according to the control signal of the controller.XSTOU DFS160-SR06-M、DFS160-SR07-M、DFS160-SR08-M、DFS160-SR09-M，DFS160-SR10-M氣動(dòng)執(zhí)行器用氣壓力驅(qū)動(dòng)啟閉或調(diào)節(jié)閥門的執(zhí)行裝置，又被稱氣動(dòng)執(zhí)行機(jī)構(gòu)或氣動(dòng)裝置，不過(guò)一般通俗的稱之為氣動(dòng)頭。有時(shí)還配備一定的輔助裝置。常用的有閥門定位器和手輪機(jī)構(gòu)。閥門定位器的作用是利用反饋原理來(lái)改善執(zhí)行器的性能,使執(zhí)行器能按控制器的控制信號(hào),實(shí)現(xiàn)準(zhǔn)確的定位。
