CPC-Cryolab has a storied history, throughout the 1960s, when CPC-Cryolab developed this line of cryogenic valves specifically detailed to support America’s quest to send a man to the moon. CPC-Cryolab’s highly engineered cryogenic valves have been used successfully in both liquid hydrogen and liquid helium applications throughout the U.S. Space program. The 5000 Series has its roots in these specially engineered cryogenic labs built for the space program and has evolved into a standard line of vacuum insulated auto- and manually-operated valves, available in one-half inch thru three-inch standard pipe sizes, routinely requested and specified globally by major Industrial Gas Industry Leaders.
