Torque is165.3Nm . | ||||||||||
Air to port A forces the pistons outwards, causing the springs to compress, The pinion turns counterclockwise while air is being exhausted from port B. Loss of air pressure on port A, the stored energy in the springs forces the pistons inwards. The pinion turns clockwise while air is being exhausted from port A. A口进气,压缩空气克服弹簧力，推动活塞向外运动，执行器输 出轴逆时针转动(0°→90°)，B口排气； 执行器失气，活塞在弹簧力的作用下向内运动，执行器输出轴 顺时针转动(90°→0°)，A口排气。 | Air to port A forces the pistons outwards, causing the springs to compress, The pinion turns counterclockwise while air is being exhausted from port B.
