Overview / Design Principle:
The D-Cryo Series is a 2-way, high flow, miniature Cryogenic valve designed and built for service down to -320ºF (-196ºC). Depending on your temperature requirements, the D-Cryo Series can be configured for liquid nitrogen (LN2), liquid carbon dioxide (LCO2), and other extreme temperature media. Teflon® coated plungers, 316 Stainless Steel guide tubes and plunger springs, encapsulated coils, and Teflon® or Rulon® seat seals produce a truly robust Cryogenic valve for applications requiring high cycle life and media temperature control.
