REVO角行程執(zhí)行機(jī)構(gòu) REVO® 系列氣動(dòng)執(zhí)行機(jī)構(gòu)是驅(qū)動(dòng)角行程閥門的理想產(chǎn)品，尤其是蝶閥、球閥和旋塞閥。此外，還可以使用在90度或者180度旋轉(zhuǎn)的機(jī)構(gòu)上。 通過(guò)一體化活塞/齒條與齒輪的嚙合，活塞的線性運(yùn)動(dòng)被轉(zhuǎn)化成為所需要的90º角行程運(yùn)動(dòng)。 所有的REVO氣動(dòng)執(zhí)行器機(jī)構(gòu)都適用于開關(guān)或者調(diào)節(jié)控制閥門。雙作用執(zhí)行機(jī)構(gòu)采用氣源從兩個(gè)方向（開啟和關(guān)閉）進(jìn)氣從而進(jìn)行驅(qū)動(dòng)，而單作用執(zhí)行機(jī)構(gòu)則是采用彈簧打開或者關(guān)閉閥門。如出現(xiàn)氣源故障，執(zhí)行機(jī)構(gòu)就回到故障安全的位置。 The REVO® brａnd is the standard for excellence and performance in actuator technology and is widely recognized in the process industries as a leader in quality and innovation. That innovation is partnered with a manufacturing excellence to drive advances in product technology. With our combined knowledge and experience we can offer the optimum actuator for any application. The REVO Series R range of actuators is ideal for operating quarter-turn valves, especially butterfly, ball and plug valves. Additional areas of applications are 90º or 180º rotary motion. The linear counter movement of the pistons is transmitted into the required 90º travel by means of the integrated racks of the pistons and the pinion. All REVO actuators are suitable for on/off or modulating control operations. Double-acting actuators are operated by air in both directions (open and closed) whilst single-acting actuators can be supplied with springs to open or close. On air failure these will then go into a fail-safe position. |
