REVO角行程执行机构

REVO® 系列气动执行机构是驱动角行程阀门的理想产品，尤其是蝶阀、球阀和旋塞阀。此外，还可以使用在90度或者180度旋转的机构上。

通过一体化活塞/齿条与齿轮的啮合，活塞的线性运动被转化成为所需要的90º角行程运动。

所有的REVO气动执行器机构都适用于开关或者调节控制阀门。双作用执行机构采用气源从两个方向（开启和关闭）进气从而进行驱动，而单作用执行机构则是采用弹簧打开或者关闭阀门。如出现气源故障，执行机构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.
