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
  • 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: Polypropylene (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): Valve is always open, will only close if water based liquid rises in outlet drain line
  • 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
