REFLECTOR:Oil Congealing Problems in Lines to Front Cooler

It's a standard 3-way valve.  Plumbing and mechanical suppliers have scads
of them, McMaster Carr among others.  There's various iterations but, when
centered, it can have both side closed or open (but not on the same valve).
Most will allow a fractional flow, such as 75% to one side and 25% to the
other, depending on handle position.  

Of course, none, when centered, will do 100% both sides as that would seem
to be 200% of total flow which, my rudimentary math and physics says, won't
happen.  You can check the seat materials but there's a wide selection that
will tolerate the heat and petroleum environment.

In effect, the valve would just be used as a proportioning valve.  Has
anyone looked at the vacuum controls used in vehicles for controlling valves
that need proportional control for things like air temp control?

Ever the conformist, I too am in favor of more heat up least in
the winter.

Tilton makes a good one for this application

Pull the oil out of the sump through a standpipe threaded into one of the 
drain points.

Does anyone know of such a valve?  Like a balance control on a stereo - all 
the way left is 100%A/0%B, centered is 100%A/100%B, all the way right is 
0%A/100%B.  It could make for a nice system.
