Overview / Design Principle:
The B-Cryo Series is a 2-way miniature Cryogenic valve designed and built for service down to -320ºF (-196ºC) in applications needing a CV between .045 and .440. Depending on your temperature requirements, the B-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.
Applications :
Environmental Chambers - Food Processing
- Laser Surgical Equipment
- Semiconductor Manufacturing
