One point to note is that kovar is used for valve pins on glass-based valves such as B9a and B7a types . Kovar has a similar temperature coefficient to glass and contracts/expands with it according to temperature . The problem is that once the valve is placed in the freezer the pins will contract as will the glass so this would carry a definite risk of air leaks and loss of vacuum (please correct me if I'm wrong!) . Cryo I guess would freeze the whole valve instantly , whereas placing the valve in a freezer would gradually lower the temperature . Is freezing a possibility for shortening valve life with absolutely zero benefits for sonics ? I can see no scientific reason why freezing would have any benefits whatsoever .
