valve picture & question

an old wrench puller

Like a lubricated plug cock. Or maybe just a plug cock. in eather case, yes, you should beable to close this to isolate. It might also have a built in check, but i dont belive so, can you try another picture?

Valve picture and question

what type of valve ,balance can i close this to isolate .first time with camera phone on 3 way mixing valve

Charlie from wmass

looks like a flowcheck to me but kind of a grainy picture. is there a nipple and cap off the bottom? How is the water flowing into and out of this thing?

I tried to lighten it up,

but still not very good.
My guess is some sort of PRV with built-in strainer that can be cleaned through the top?

Dezurik

Looks like a Dezurik or equivalent plug or balancing valve. Crane, Hammond and others made plug valves also.
