Soft-closed GV5 (10-15 psi), Soft-closed GV18 (414 seconds) -> for viewport work by others 
After 45 minutes or so, GV5 "cammed" closed -> As such, I went ahead and valved-in the YBM MTP for the weekend.  

For future reference;  use 5-10 psi for GV5 soft close instead of 10-15 psi (each pneumatic valve is unique, observed range varies between 15-25 psi to cam close)

Correction -> 4 minutes and 14 seconds not "414 seconds" as listed above. 

Also, 80K pump pressure may indicated that GV18's gate may not be in full contact with its O-rings?  Should have actuated valve motor for a few more seconds for effective soft-close?
