[PSUBS-MAILIST] Alec's new valves

Sun Oct 28 17:42:32 EDT 2018

Hank,
I would be interested in seeing them when they are finished.
Attached is one of my preliminary designs, but will probably
make the Aluminium housing a tight fit around the wires as 
a heat sink. Being vent valves they won't get water cooled till 
the ballast tanks are flooded.
