 Jon, I'm repeating myself here but I am well on the way to a good solution. It is an adjustable air compensator that uses a second stage regulator valve. So the delivery rate is the same as a second stage regulator. I have replaced the flimsy second stage diaphragm with a 80psi rated diaphragm I had made up for me. Minimum run was 40.I am printing the body on a resin printer with tough resins suitable for sea water. I need to order in some suitable stainless springs & fittings, & twink the design.A hose from it goes to a manifold so it can service several components simultaneously. I am building an electric manipulator, so will have air compensation on that but oil compensation on my thrusters. Both pressurised by the same air system.The air pressure over the oil will allow for expansion. No bellows required.Alan
