Picture of Sanitary Veritical Check Valves

Vertical Line Up-Flow, Low to High Flow, Springless, Crevice-Free

Two-piece, spring-less sanitary disc check valve for vertical up-flow for bioprocess media and purified water applications for the biopharmaceutical, pharmaceutical, food & beverage and consumer health & beauty industries:

WFI loop, pump out: vertical line up-flow, downstream of pump
WFI loop, standby pump - validation: vertical line up-flow, downstream of standby pump with precision bleed for back flow of hot WFI bleed
Media/Buffer Prep: back flow prevention during dilution or pump out
Bioreactor: vessel bottom inlet sparge line back flow prevention
Process vessel: over pressure and vacuum protection upstream of vent filter
F & B and consumer H & B process inputs, outputs, purified water and clean utility back flow prevention

Features & Benefits

Removal of traditional spring and guide:
- eliminates area where bioburden and bacteria can accumulate
- potential for particulate generation
Very low cracking (opening) pressure
High flow rates with minimal pressure loss at increased flow compared with mechanical return check valves
