Facing the end of a valve stem the convention for valve design is turning clockwise tightens or shuts the valve while counter-clockwise (anti-clockwise for our foreign friends) loosens or opens the valve.  Its the righty tighty, lefty loosey convention. 

For you diesel submarine types:  Name at least 6 valves that work in the opposite manner; ie: righty loosey, lefty tighty.

For your nuc types: Name at least 4 valves which work in the opposite to the convention.

For you folks who subscribe to the DBF/screw the nukey-poos, name at least 10 valves that work opposite to the convention and describe why they do so. (for the nucs, they 'why' would be extra credit)

Till next week
Stay warm

Note:  This question addresses only valve that have a 'screw type' valve stem. Sleeve, flapper and other such valves are not included in the correct answer set and trying to sneak them in as 'semantics' will result in a clearly angry look from me.

One lefty tighty valve is on the cold water tap on bathroom, kitchen and service sinks. Hot water is lefty loosey.

Ok, hint for the diesel boat guys.  Gato, Balao, Tench, Salmon classes and possibly Tang and Barbel too.

Each interior watertight bulkhead had one of these.

Salvage valves, if I remember correctly, fitted into watertight bulkhead, operable from either side, admitted 700# air to pressurize either compartment.

That is correct and takes care of a bunch of them.  Now, there are a few that are common to both diesel and nuc boats.

Keep going.

High and low salvage valves, one of each in each water tight compartment.To open, turn clockwise inside the hull; counter clockwise outside the hull.
Finns may have faults,but being wrong isn't one of them.
