Two-Way & Three-Way Line Blinds (LB)

The LB Series Line Blinds are used when there is a requirement or need for two distinctly different fluids to flow through a common line at different times. The most common use is to keep water and carbon dioxide (CO2) separate in an injection system. This product is also used in the marine industry, power generating plants, natural gas plants, and liquid storage terminals.
