Need the number for the Norgren Pressure relief valve
 

We are a 3rd year team and per this years kit, didn't get a new compressor, shock asorbing feet or the pressure relief valve that comes with the compressor.

Now ...we have a compressor but the pressure relief valve has been lost or misplaced (two schools were using the 2002 robot for teaching purposes, you know how it goes)

The Norgren company tells me that the part number for the valve should be stamped on the valve. Can someone please check their compressor and take a look at the brass valve with the little holes in it, and tell me the number
I would greatly appreciate it. We don't want to canabalize our 2003 Bot.
I just want to buy another valve.
thanks,
