How big is the hose in and out from this valve? How is the valve
operated? How much space is available? is alternate space available by
rerouting adding/cutting hose?
If it is air or vacuum operated, (or mechanical or electrons) you should
be able to find an industrial valve and an appropriate operator made out
of durable materials, like brass/bronze, with brass hose barbs. That
will last longer than the truck...
Will a solenoid valve work, (on/off) or does it need to be regulated?
(globe, ball or butterfly valve?)

I sent ya off for research, huh? Good job!
Thank you.
What all this shows is the Gilbreths were interested in making things more
efficiently and faster.
What Deming was interested in was making quality things.
All the difference in the world! I will take quality over faster.
I'm struggling with that right now on our Kenworth W900. After 18 years,
the rubber tubing in the water valve for the cab's heater failed. I
purchased the "replacement" for it last year when The Shop in Moriarty
fixed the no-heat problem. That valve has now failed.
The original valve had a durable non-metallic material body onto which
the copper inlet and outlet hose barbs (with square flanges of the same
type durable non-metalic material) fastened to the body with four screws.
The "replacement" was all made of some type of hard plastic, with one of
the plastic water barb molded to the body and the other plastic water barb
pressing into the body and an internal molded neoprene "o-ring". I'm not
sure how it was supposed to be fastened into the body, since I have only
looked closely at it since it failed: The separate plastic hose barb came
loose from the body and started leaking profusely.
I can take and send pictures if y'all are interested.
I'm still looking for a good solution.

BTW the book "12 is Enough" is entertaining. It is about the Gilbreth
family.

Q: Why are many of the US built wretched ricebox cars better
built/reliable than American iron and the Alabama spawn of of DBAG?
A: Because W Edwards Deming was asked by the Japanese to help them
build better products. He taught them well. He also taught the
Americans during WWII. After the war, the American companies threw
out what he taught them and the women who did the SPC in the plants.
They went back to therbligs. The american bean counters liked
therbligs. They were still using therbligs in the 70s and into the
80s. The Japanese listened well, learned well, and did NOT throw
out the systems, but improved on them. Look up the case of the Ford
transmissions built by mazda in the 80s.
