Radiator Isolation Valve
Our new radiator isolation valve is a three-way cooling
system valve used on the Space Shuttle. The valve's primary function is
to allow for re-routing of the freon loop from the radiator panels into
a return reservoir, which may be necessary if the radiator panels leak
during flight. Two valves will be installed in each orbiter. The valve
is a derivative of our bypass valve and flow control valve, which have
been in service in the freon loop since the inception of the Shuttle program. |
