BURKERT气动调节阀用途及特点:
A、气动调节阀的用途与特点用途 是一种直角回转结构，它与阀门定位器配套使用，可实现比例调节; V型阀芯适用于各种调节场合，具有额定流量系数大，可调比大，密封效果好，调节性能灵敏，体积小，可竖卧安装。适用于控制气体、蒸汽、液体等介质。
B、特点：是一种直角回转结构，由V型阀体、气动执行机构、定位器及其他附件组成;有一个近似等百比的固有流量特性;采用双轴承结构，启动扭矩小，具有极好的灵敏度和感应速度;强的剪切能力。
C、气动活塞执行机构采用压缩空气作动力源，通过活塞的运动带动曲臂进行90度回转，达到使阀门自动启闭。它的组成部分为：调节螺栓、执行机构箱体、曲臂、气缸体、气缸轴、活塞、连杆、万向轴。
D、气动调节阀的工作原理：气动调节阀由执行机构和调节机构组成。执行机构是调节阀的推力部件，它按控制信号压力的大小产生相应的推力，推动调节机构动作。阀体是气动调节阀的调节部件，它直接与调节介质接触，调节该流体的流量。
