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.
