[PSUBS-MAILIST] Alec's new valves

[Alan via Personal_Submersibles]

Hank,
I would need to put a seal on the plunger & as the plunger goes
in & out it would be displacing oil, so have the same problems as with
linear actuators. As the plunger has to be a material that can be
magnetised it is vulnerable to corrosion, so I will have to coat it in
resin anyway. It is just a matter of putting the plunger on the lathe
& taking off enough metal to make room for the resin. 
I made a solenoid valve years ago. It was 60W & got hot really fast.
I have ordered a 48V & 24V solenoid mainly to see how hot they
get, how strong they are, what gauge wire they are using & how many
turns. If neither is suitable at least I will get some ideas for building one.
I have been inspired by those little open waterproofed motors I bought.
What were you going to use the solenoids for? If you want I will keep
you up to date with what I am doing, but the solenoids will take about
2 weeks to get here.
Alan
