Change in Cryogenic Freezer Purge Valves

The 3 way purge valves, part number 10712933 and part number 13284954 are the two different types of cryogenic valves. The old valve (10712933) had spade terminals for push on connectors and the new valve (13284954) has wire leads to interface with the new TEC3000 controller wiring harness, this is the only difference between the two or else the valves are the same. While the new valve is used on all TEC3000 cryogenic freezers, the old valve is still used on the Bio Series and CDC cryogenic freezers.
