Sporlan Reciever Bypass Valve Info

[MikeySq]

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:D

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??

Thanks
Mike

Here's the old site.

That is Mr. Schoen's site as I mentioned above, i just don't see it in there anywhere, my navigational skills are a bit weak now i think!:p


I tried to find it in the Literature section on Andy Scohen's site and didn't find it,

I was skim reading. Saw parker and got andy's site.

Sorry.

It sounds like you're referring to what Hussmann called the "Auto-Surge" valve.

I found a mention of it in Hussmann's SuperPlus Manual, which is linked to in the EF (under "discontinued"):

http://www.hvac-talk.com/vbb/showthread.php?t=163158

...or here's the direct link:

http://www.hussmann.com/docs/inst_manuals/discon/refrig_d/SuperPlus.PDF

(See Fig 2-16 on p. 29)

If it's a Sporlan it's probably an OEM special, so Andy Schoen will be along shortly to ID it for you. ;)

Thanks Ice, I knew you allways have all the linkshttp://www.hvac-talk.com/vbb/images/icons/icon14.gif

I'll have to read the links later to see for sure, I'm kinda rushed now I gotta run to Buffalo, got tix for the Pats/Bills game, I just got back from the store to see if it was running OK and hopefully it's not going to bother my co worker who is covering my "on-call" while I'm at the game

But auto sounds right, I was calling it a Mechanical Surge Valve?? lets hope its not discontinued or just a proprietary hussmann valve??? if so looks like I'm going to pull the guts and do a little ball valve magic hahaha

as you can see by my 1st post and 2nd that's just a little showing of how much sleep I'm on in the past couple days

Raise your hand if you love neglected supermarkets!!! hahahahaha:D:D:D:D

You're welcome.

I'm sure this is our valve... a 3-Way valve with essentially a TEV pilot. We called it a Y977-1 as I recall. I'll post additional information about it when I get back to the office tommorrow. It's been obsolete for some time, and I wouldn't have any information on it on my site.

[MikeySq]

Thanks Andy!

What a cold game, I was up on my feet and jogging in place at times, burrrr, long live Ralph Wilson Stadium!

See that play at the end of the 2nd???? total BS!!!!!

From the Hussmann pdf(thanks again ice)
The valve fails to bypass mode, to reverse this you have to put suction pressure to the port that gets discharge pressure normaly and that will push slider to the normal mode via equalizing pressure, from drop leg.

would it be better to open valve and remove slider and valve off surge line by the ball valve thus removing all pilot lines, or would you think that may cause more problems?? I think that is what I'd prefer to do.

I'll just need to get a new set of seals to do this, and I'm thinking a seal kit from a normal 3 way valve may work, the body looks to be very similar.

Forcing the system into surge mode should resolve the problem. The bypass mode was an energy saving technique.

I seem to recall we used the 8D, 12D and 16D 3-Way reclaim valves with the Y977-1 pilot. I'll try to remeber to look this valve up tommorrow. Andy

Thanks Andy, I can say now I actually know how to pronounce your last name, Stopped by the Sporlan office in Toronto today the guys there said they know ya. Actually Bob gave me a nice red Sporlan Binder with a bunch of Bulletins and nice labeled partitions:) I picked up the lower body gasket and the pilot tetra seal there.

The Valve pilot was partially worn but it says SDS-12-D I think there were letters after the last D, the date stamp on it is 5/98. If you have a bulletin on that one that would be cool.

I pulled the slider piston and shaft from the main body, I put 3 1/4" MPT plugs in the pilot head where all the fittings went and it's good and tight. I also had to disassemble the slider and keep the lower machined part that lines the body to the base so the lower O-Ring would stay put and be tight, but, in all it worked great.

Up here in this part of Canada Free subcooled liquid is readily available especially this time of year, as for getting it up and running again this customer is cheaper than a 45 year old Vegas hooker that has gonorrhea, so it's probably not going to happen.:p

Andy .....if you come across some older bulletins and you come across ones for the Sporlam made for Hussmann Oil Differential valve(the one that looks like a TX) and a bulletin for the old obsolete ORIT20 65/225, and CROT valves for used for condenser flooding. I took the last available new old stock ORIT65/225 pilot available at Sporlans warehouse here in Canada today and I'm told they're no longer available,
that would be greatly Appreciated!

Mike, it was a special we made for Hussmann. We made an SDS-8DC, SDS-12DC, and SDS-16DC, modifications of our 8D, 12D, and 16D "C" type reclaim valves respectively. They all used our K-Y977 pilot assy. As you've discovered, these items have been obsolete for some time.

We never published any technical literature on these valves as they were specifically made for Hussmann.

FYI, with a little bit of effort, you could also replace the pilot with the appropriate reclaim valve pilot and operate it electrically, say hook it up to a thermostat and operate it based on ambient temperature... and have your own homemade autosurge valve. :p

Mike, you may find this bulletin of interest: http://www.jandrewschoen.com/andysfiles/F90-30-4.pdf

Regarding the Y825-2 oil differential valve, this was another valve we made specifically for Hussmann, and we haven't published any technical literature for it. But it is functionally equivalent to our Y1236-C oil differential valve: http://sporlan.jandrewschoen.com/110-10.htm

that's exactly what i was thinking, i'm not sure but it's possible the rack controller may be able to calculate subcooling and operate it by an existing spare relay on one of the boards? I may look in to it if i get a chance

You're welcome.

i knew there was reason i liked you

tranplant pats fan :mad: from N.H.

[MikeySq]

gutted another one today, this time it was flowing in both directions! it was alot cruddier inside than the last one I did. glad i picked up a 2nd set of seals when i was at sporlan for the last set!

[MikeySq]

pics of one in use and another one that i gutted due to a broken power element capillary
