Valve Speed

Some one asked how fast the valves move with these actuators.    I did a test this morning with a 6 cell NiMH battery.

Here is a full speed video of an open/close cycle with no pressure:

Here is the same video at quarter speed:

Here is a quarter speed video of a second test at 750 psi line pressure:

With no pressure, the average frame count of the open and close was 8.5 frames which corresponds to 0.283 seconds/90 degrees

With the 750 psi line pressure, the frame count was 9.5 frames, or 0.317 seconds/90 degrees.
