ABSTRACT:
A diaphragm valve for use with cryogenic systems controls the flow of cryogen and is capable of operating at high pressures for extended periods of time. The diaphragm consists of a polyamide film sandwiched between to manifold sections. A pilot valve controls the pressure of cryogen against one face of the diaphragm to open and close the diaphragm.
