DRG系列气动执行器   

DRG eries Pneumatic Actuator

DRG 系列

DRG 系列拨叉式气动执行机构适用于 90°行程阀门(如球阀、蝶阀、旋塞阀)的开关切断或计量控制,可结合各种附件实现工业过程自动控制。其原理是压缩空气进入气缸，推动活塞作直线运动，利用销轴与拔叉滑槽的传动结构将活塞的直线运动转化为拨叉的旋转运动，并带动输出轴转动，从而实现对阀门的控制。

DRG scotch yoke pneumatic actuators are fit for turn-off or metering control of 90 valves (suchas ball valves, butterfly valves and plug valves). lt can realize automatic control of industrial processwith various accessories. The principle is that compressed air enters the chamber to push the pistonto do linear motion, the piston's linear motion will be converted into the yoke's rotary motion bytransmission structures of the yoke pin and yoke groove, and drives the output shaft to rotate, thusachieving the control of the valve.

DRG 系列拨叉式气动执行器有对称式和倾斜式两种类型，对应两种不同的扭矩输出特性。对称式的拨叉机构，具有更加平衡的扭矩曲线，主要适于球阀、旋塞阀的控制。     

There are two types of DRG scotch yoke pneumatic actuators: symmetrical and inclined, whichcorrespond to two different torque output characteristics. The symmetrical yoke mechanism

我司生产的气动执行器广泛应用于石油和天然气、化工、炼油、纸浆和造纸、水处理、电厂、煤化工等行业。

Our pneumatic actuators are widely used in petroleum and natural gas, chemical industry, oilrefining, pulp and paper making, water treatment, power plants and other industries.
