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
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,日历日
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.
