濟(jì)南裝載機(jī)調(diào)節(jié)閥在過程控制中的作用是眾所周知的，在許多控制過程中要求調(diào)節(jié)閥在故障時(shí)處于某一個(gè)位置，以保護(hù)工藝過程不出現(xiàn)事故，這就要求調(diào)節(jié)閥在設(shè)計(jì)上實(shí)現(xiàn)安全的三斷（斷氣、斷電、短信號(hào)）保護(hù)措施。對(duì)于電動(dòng)調(diào)節(jié)閥來說，比較簡(jiǎn)單，斷信號(hào)時(shí)，可以根據(jù)控制模塊的設(shè)定而停留在全開、全關(guān)、保持中的任一位置，而斷電時(shí)，自然停留在故障位置，或帶有復(fù)位裝置的電動(dòng)執(zhí)行器也可將閥位運(yùn)行到全開或全關(guān)。
Jinan loader regulation process control valve is well known, the process requires many control valve when a fault in a position to protect the process is not an accident, which requires the design of the safety valve on the realization three broken (breathe, power, SMS number) protective measures. The electric control valve is relatively simple, the interrupt signal, the control module can be set according to the desired fully open, fully closed, remain in any one position, and when power failure to stay in the natural position, with or without there reset device electric actuator valve can also be run to the fully open or fully closed.
