What's inside an os&y valve?

Disassembling a 6 inch gate valve that I definitely did not steal from a Dave & Buster's in Providence, RI. What is an os&y and what is it used for? what does os&y stand for? watch and find out. Also, did you know that it sounds very strange to hear your own voice recorded and played back to you?

Is there a way to service or grease up the stem on the gate valve... or easier to swap it out???

[@beaushepherd3890]

Yes, grease the threads with a food safe grease and exercise it. Assuming you’re talking about an OS&Y
