Apeks First stages greater IP at depth

lbihler · 2nd February 2006, 10:36

I know the subject has been discussed before but I cannot find the original thread using the search (don t

too hard please), anybody would have any document reference/ any experience on the impact of the IP increasing at depth on the solenoid (damage ?) and / or the ADV (Free Flow?) ? and on a detailed procedure on how to modify a DS4 into a US4 ?

All my OC regs are APEKS with DS4 or FST first stages and I m about to order a meg

, I would just like to know if I can use these without problem or if I can/have to modify them

.

You may need to get some high quality swivels to route some of the hoses.

Have a look at http://www.mj-engineering.com/

I am using Poseidon regs with a built-in OPV. Can't see why you couldn't use clean DS4, or US 4's.

Stuart's breakdown is so informative and an excellent reference piece.

That the top ring off that holds the sealing diaphram remove the diaphram and the plunger. It would make a crude conversion.

Seems like each time this question comes up it's with regard to a Meg.

Has anyone asked Leon whether or not the increasing IP is a problem for the oxygen solenoid?
