Vertical Line Down-Flow - For Liquid Drain Lines, Low to High Flow, Springless, Crevice-Free

Two piece, spring-less sanitary check valve for vertical liquid down-flow installations. Bioprocess drain lines are a common application. Note that liquids must have density/specific gravity very close to water. Applications areas are:

WFI point of use: back flow prevention, below point of use valve
Media/buffer prep: back flow prevention during dilution, drain line back flow prevention
Separation: centrifuge waste line to drain, back flow prevention
Purification, chromatography: waste line to drain back flow prevention
Agitator or pump seal water outlet to drain back flow prevention
F & B and consumer H & B process inputs, outputs, purified water and clean utility down line back flow prevention

Features & Benefits

The first and only vertical down flow sanitary check valve that is normally open and continuously self-draining
Removal of traditional spring and stem guide:
- eliminates areas where bioburden and bacteria can accumulate
- potential for particulate generation
Very lock cracking (opening) pressure
High flow rates with minimal pressure loss at increased flow compared with mechanical return check valves
