双作用执行器动作原理
正作用
A口进气，压缩空气推动活塞向外运动，使执行器输出轴逆时针 旋转(0°→90°)，B口排气。
B口进气，压缩空气推动活塞向内运动，使执行器输出轴顺时针 旋转(90°→0°)，A口排气。
反作用
A口进气，压缩空气推动活塞向外运动，使执行器输出轴顺时针 旋转(0°→90°)，B口排气。
B口进气，压缩空气推动活塞向内运动，使执行器输出轴逆时针 旋转(90°→0°)，A口排气。

双作用执行器的选型:在正常操作条件下，双作用执行器考虑的安全系数为20%-30%。
示例：
阀门力矩=100Nm
安全力矩=100×(1+30%)=130Nm
气源压力=5Bar 对照双作用力矩表，选配双作用执行器小规格为RT160DA。
