Abstract

The usual cryogenic valve is a modification of a conventional valve. As such, these valves frequently have a number of drawbacks including large heat leak, large cold mass, leakage, etc. This paper describes a valve which has been specifically designed, constructed, and tested for use in small liquid-helium transfer lines. It is welded into a straight section of transfer line and increases the cold mass by the equivalent of one foot of line. The valve is of welded, all-metal construction and has a modified ball-and-cage design. A standard valve solenoid is used for actuation and is mounted outside the vacuum space.
