Symbol on side of Globe Valve
Symbol on side of Globe Valve
(OP)
Hello all,
I ran into a question today concerning a symbol located in the casting of a globe valve. In fact it is on every globe valve we are installing.

I hope the symbol above makes sense to someone out there. We have been racking our brains all day searching catalogs and the net to no avail.
Any help would be appreciated!
Thanks!

RE: Symbol on side of Globe Valve
Manufacturer's usually call a globe valve a bi-directional valve since the throttling characteristics are the same in either direction. In steam plants we were really careful to ensure the flow was up, but in Oil & Gas it is rare to find someone who knows what the symbol means.

IMHO this symbol does not represent the flow through the seat as mentioned by zdas04, but the internals of the valve in a cross-sectional view. The horizontal line represents the disc.
Thus the normal flow (up through the seat) would be from left to right.

This is what I had in my mind and had a slew of pipers telling me different. I will pass the information from your link on to others.
Thanks again!
