Big red button and four smaller valve actuators, one for each corner. Mike Ellis says that it was a Newell in house valve body used before they outsourced to another vendor part for automation in the mid 80s. 
Has anyone used this system and how is the best way to use it properly.  I’m putting together a parts kit for o-rings etc... any information you have would be appreciated.

FYI,  I included a picture of the part.
