RK系列执行机构是以干燥、清洁的压缩空气为动力，输出轴回转角为90度的角行程气动执行机构。该产品分为双作用和单作用型两种，与球阀、蝶阀、旋塞阀、偏心旋转阀等阀门组合成气动控制阀，也适用于回转运动的其它装置。
特点
① 采用双活塞式齿轮、齿条结构，效率高、体积小、重量轻
② 单气控型采用多弹簧结构，使双气控型和单气控型外形尺寸相同，达到零件完全互换的目的
③ 在需电磁阀控制时，电磁阀可在气缸外壁直接安装，无需外接气管
④ 单气控型执行机构的弹簧预压至设定的位置后，安装在气缸盖内，可方便、安全的增减弹簧数量
⑤ 气缸采用铝合金拉制成型，内表面经特殊工艺处理；活塞多导向结构设计，用低摩擦非金属材料做滑动轴承，避免气缸内壁与金属材料直接接触；齿轮精确加工；齿条精密铸造；确保整机动作灵敏可靠和长久的使用寿命
⑥ 通过两个限位螺钉能在0°和90°两个位置进行±5°的微调
