Hello everybody,

Im attaching two pictures of two different Edwards Thayer valves. Each one has different keys (one with straight iron tool and other with S or Z shape).

Do you know the difference between them in terms of action, speed, longer or shorter air route, spring tension, etc.) And which one would you recommend best?

Thanks for your time.

How exactly would a different lever shape impact air route length at all?

I do not know if Edwards still uses the linkage pictured on top. Most seem to have the more angled one like pictured on the bottom. It also is entirely dependent on the geometry and shape of YOUR hand, so any advice that is offered here could not apply to you at all.
