So are you guys seriously telling me you don't have any experience with pneumatic valves and/or Habonim products ? How about data on using solenoid valves in a sub? It seems to me that solinoid valves would use up a fair bit of electricity when left in the open position.

PSUBS.ORG PO Box 53 Weare, NH 03281 603-529-1100 ************************************************************************ ************************************************************************ ************************************************************************I've been looking for and considering what types of valves will work best in a fly by wire computer controlled sub design. I've been looking at the various designs Paul Moorhouse has produced and I found some data on the remote controled valves he used on Alicia."The Habomim COMPACT pneumatic quarter turn actuator has been developed to be simple, reliable, and efficient using a patented rack and pinion design.
Four separate racks, each with its own piston, develop torque around the centrally located pinion. "Here is the links to view the Habonim valves used on Paul Moorhouses Alicia Sub Design. I'm very interested in the larger exhaust valve he used for the diesel engine. In the internal pic of the engine room on Alicia, it's the large valve in the center with it's blue pneumatic actuating part hidden behind other parts. It is not hooked up to the engine in that pic. I'm not sure I like having only one valve on the exhaust, and having no manual override valve. I would like to know if this brand or any other brand of pneumatic valve can be used externally on a sub used in saltwater?
Note: Compact-I is in phase out stage. So the Compact-II looks to be it's replacement. Has anyone here used this type and/or brand of valves, and did you like there performance?Regards,Brent HartwigImagination is the one weapon in the war against reality.-- Jules de Gaultier
