''NO REPLACEMENT OR ALTERNATE VALVE''
At this time, there is NO replacement
for the temperature control valve,
and we should continue using
the V47 described here.
I keep looking for a decent replacement;
BUT THIS IS A VERY SENSITIVE
CONSTANT EQUILBRIUM TYPE VALVE
I am working on a PWM solenoid valve.
The PMW valve will do just fine
at a fraction of the cost of the present V47,
but it needs some finishing.
and I will be running late on all other projects.
I sincerely apoligise for this twist of events,
but once the website is completed,
things will all fall into place.
