Can anyone tell me about the Selective Control Valves on (+)

the Draeger Ray. I'm always looking for bits and pieces for a homebuild project and there are a couple of these up for sale. Not sure exactly what they selectively control. Did a search but can't come up with details. Any help appreciated.

What's a selective control valve? Do you have a link to one?

Maybe an adjustable needle valve rather than a fixed orifice?

Like the one used by OMG on the Azimuth or Tubby on his CCR Dolphin.
Depending on the implementation they allow you to either adjust the gas
flow infinite/small steps (for use with mixes between min/max O2) or
during the dive.

If I had a link I could probably figure it out but I haven't been able to find anything about it on the net. I was browsing through a popular website here in the Northeast and they mentioned having a bunch of Draeger Rebreather accessories for sale "CHEAP". Figured I might find something interesting and emailed. He said he's only got these left. I've sent an email trying to get more info.

I was thinking they might be an adjustable valve of some type as well but couldn't quite track down what it was on any of the Rebreather sites or Ray sites.
