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
  • Size: 1/2″ – 3″ (DN15 – DN80)
  • End Connections: ASME, DIN, ISO Tri-Clamp and Tube Weld Ends
  • Cv (Kv): 3.5 – 58.6 (3,03 – 50,7)
  • Wetted Material: ASME SA479 316L (UNS 31603) is standard. EN 10272:2000 GR 1.4435, AL-6XN®, Hastelloy C-22 and others are optional
  • Disc Material: 316/EPDM, Teflon, PEEK (all materials FDA and USP Class VI)
  • Gasket Material: Various (all materials FDA and USP Class VI)
  • Max Pressure Temperature: 230 psi @ 100°F (16 bar @ 38°C); max temperature dependent on disc and gasket material
  • Cracking (opening pressure): Polymer Discs: 0.04 psid (2,76 millibar); 316/EPDM: 0.13 psid (8,76 millibar)
  • Metallic Surface Finish: Wetted parts: ASME BPE SF5 20 Ra µin (0,5 Ra µm) electropolished; standard 8 Ra µin (0,2 Ra µm) electropolished optional
