This post was last edited by *aodai536 on 2012-4-11 at 11:24. R refers to the angular travel, while A is the model of the cylinder – there are A and B versions. I’m not sure what DA means. It seems like the character count wasn’t enough; is it sufficient now?
DA stands for double-acting pneumatic actuator!! DA stands for double-acting pneumatic actuator!!
double action, double action, double action
Has the poster made a mistake? In KOSO, RA refers to angular travel, LA refers to linear travel; R stands for reverse action, and D stands for forward action. There is no such thing as DA. For example, 501T-524L RA DN: RA stands for angular travel, D stands for direct-acting, and N stands for having a handwheel.
I just saw it today as well; indeed there is a DA. There are two ways to represent the spring range: DA and RA, which actually refer to positive action and reverse action respectively.
The DA is a double-acting actuator whose function is to open and close the ventilation. Together with the valve body attached to it, they form a complete pneumatic valve
It means the positive effect; I don’t know if there’s a number after DA? If there is one, it should be the size of the actuator.
DA should refer to direct action, while RA should refer to reverse action.
