"With ValveGear Constructor, you achieve
your layout goal much faster. You avoid
playing around with all the detailed values."
"... achieved a good result within
half an hour, without any
enhanced previous knowledge."
"... silky smooth running in both directions ..."
"... we really rode using the reversing instead of
the steam throttle valve. Straight forward very
uniformly at 40 to 45 percent cylinder filling ..."
"... when in a curve, you raise the
cylinder filling and do not need to
move the steam throttle valve."
"... really good and very helpful ..."
