概要 GENERAL
KOSO TORK系列是一种中等输出力、高性能的气动执行机构,分为双动作和单动作两种,与角行程调节阀组合使用,可用于调节和开关的场合。
该系列也可用于其它回转( 90°)的场合。KOSO TORK double acting and spring return pneumatic cylinder actuators are powerful, high-performance actu-ators that provide positive modulation or on-off operation for rotary stem motion type control valves and many other quarter-turn ( 90°) rotating mechanims.

bruce特点FEATURES
□单动作型及双动作型执行机构均以输出轴为中心呈左右对称结构,因此可以稳定地安装在阀体上。
□单动作型执行机构的动作变更时,因传动轴两端的连接尺寸相同,根据需要可以方便地选择在通气的情况下输出轴左转或右转。
□单作用型执行机构的弹簧被安装在固定的气缸盖内,并被预压至设定位置,所以可方便、安全地进行拆卸或组装。□

For both double acting and spring return types, the unit is symmetrically structured around the drive shaft. This allows easy and stable mounting of the actuated part.
Spring return type’s action direction change is easy, since both ends of the drive shaft have the same dimensions and the top and bottom mounting ats are dimensionally identical. Direction can be changed by simply switching the side on which the actuated part is mounted.
Spring-return’s springs are multi-spring type and each spring is pre-compresd. This makes disasmbly and asmbly easy and safe.
