I'm looking to see if anyone has the sporlan bulliten for a particular valve i need info on. I tried to find it in the Literature section on Andy Scohen's site and didn't find it, and I just finished a 17 hour day so i'm not going to even attempt the parker site now
The valve in which I speak and I apologize for being vague, but this is a 3 way valve in the condenser outlet (drop leg) after the flooding valve. It's purpose as far as i Can tell is to bypass the receiver to take advantage of extra sub cooling in low ambient conditions. Totally self contained/controlled, ie non electronically controlled surge valve.
it looks sort of like a normal sporlan 3 way with the exception of a pilot actuator thingy that had a Tx valve like power element which senses drop leg temp it also uses suction pressure, discharge pressure and a pilot line sensing cond out pressure.
I've only seen one of these valves before on a couple other racks of the same age. Canadian built Hussmann circa 1998
BTW if you're familiar with this valve what do you see when the power element cap breaks off, stuck in bypass??
