對于雙作用的氣動、液動、電動執(zhí)行機構，一般都沒有復位彈簧。作用力的大小與它的運行方向無關，因此，選擇執(zhí)行機構的關鍵在于弄清的輸出力和電機的轉動力矩。對于單作用的氣動執(zhí)行機構，輸出力與閥門的開度有關，調節(jié)閥上的出現的力也將影響運動特性，因此要求在整個調節(jié)閥的開度范圍建立力平衡

對執(zhí)行機構輸出力確定后，根據工藝使用環(huán)境要求，選擇相應的執(zhí)行機構。對于現場有防爆要求時，應選用氣動執(zhí)行機構。從節(jié)能方面考慮，應盡量選用電動執(zhí)行機構。若調節(jié)精度高，可選擇液動執(zhí)行機構。如發(fā)電廠透明機的速度調節(jié)、煉油廠的催化裝置反應器的溫度調節(jié)控制等。
調節(jié)閥的作用方式只是在選用氣動執(zhí)行機構時才有，其作用方式通過執(zhí)行機構正反作用和閥門的正反作用組合形成。組合形式有4種即正正（氣關型）、正反（氣開型）、反正（氣開型）、反反（氣關型），通過這四種組合形成的調節(jié)閥作用方式有氣開和氣關兩種。
