有正、反作用功能；

移動速度大，輸(shu)出力與操作壓力有關；

可(ke)靠(kao)性高，但氣(qi)源(yuan)中斷(duan)后閥門(men)不能(neng)保持(加(jia)保位閥后可(ke)以保持)；

輸出功率較大；

具有防爆功能。

當壓縮空氣(qi)從管(guan)咀(ju)進入氣(qi)動(dong)(dong)(dong)(dong)執行(xing)(xing)器時(shi)，氣(qi)體(ti)推動(dong)(dong)(dong)(dong)雙活塞(sai)向(xiang)兩(liang)端(duan)(duan)(duan)(缸蓋(gai)端(duan)(duan)(duan))直線運(yun)(yun)動(dong)(dong)(dong)(dong)，活塞(sai)上(shang)的(de)(de)齒(chi)(chi)條帶(dai)動(dong)(dong)(dong)(dong)旋轉(zhuan)軸上(shang)的(de)(de)齒(chi)(chi)輪逆(ni)時(shi)針方向(xiang)轉(zhuan)動(dong)(dong)(dong)(dong)90度，閥(fa)門即(ji)(ji)被打開。此(ci)時(shi)氣(qi)動(dong)(dong)(dong)(dong)執行(xing)(xing)閥(fa)兩(liang)端(duan)(duan)(duan)的(de)(de)氣(qi)體(ti)隨另(ling)一管(guan)咀(ju)排(pai)出。反之，當壓縮空氣(qi)進入氣(qi)動(dong)(dong)(dong)(dong)執行(xing)(xing)器的(de)(de)兩(liang)端(duan)(duan)(duan)時(shi)，氣(qi)體(ti)推動(dong)(dong)(dong)(dong)雙塞(sai)向(xiang)中間(jian)直線運(yun)(yun)動(dong)(dong)(dong)(dong)，活塞(sai)上(shang)的(de)(de)齒(chi)(chi)條帶(dai)動(dong)(dong)(dong)(dong)旋轉(zhuan)軸上(shang)的(de)(de)齒(chi)(chi)輪順時(shi)針方向(xiang)轉(zhuan)動(dong)(dong)(dong)(dong)90度，閥(fa)門即(ji)(ji)被關閉(bi)，此(ci)時(shi)氣(qi)動(dong)(dong)(dong)(dong)執行(xing)(xing)器中間(jian)的(de)(de)氣(qi)體(ti)從管(guan)咀(ju)排(pai)出。

意大利G.T.Attuatori成立于1963年(nian)，總部位于米蘭(lan)，致力于開(kai)發和生(sheng)(sheng)產(chan)氣(qi)動執(zhi)行器(qi)及相關配件(jian)，產(chan)品(pin)(pin)主要用(yong)于先(xian)導和執(zhi)行器(qi)的(de)裝配。幾十(shi)年(nian)來GT ATTUATORI分布世界各(ge)地，如今GT ATTUATORI已經是(shi)氣(qi)動執(zhi)行器(qi)最(zui)大的(de)制造(zao)商。GT ATTUATORI生(sheng)(sheng)產(chan)過程的(de)長久性(xing)提高(gao)以及根據ISO9001品(pin)(pin)質管理保證(zheng)了產(chan)品(pin)(pin)的(de)功能和高(gao)可靠性(xing)。
