VG-10 valve
Full-size fixed valve

VG-10 full-size fixed valve
  • Large opening size for improved
    fouling resistance
  • Extended time between shutdowns
  • Fixed opening means the valve
    cannot stick shut like moving valves
  • Easy to clean; less downtime
  • Rugged, durable construction for
    long tray life
  • Can be made of materials up
    to 0.25" (6.35 mm) thick for
    maximum resistance to corrosion

 

This is a full-size fixed valve that is anything but conventional.

  • The net rise typically ranges from 6 mm [0.236 in] to 14 mm [0.551 in], varying in 1 mm [0.039 in] increments. Other lifts may be available in some cases.
  • This valve is also directional with the rear leg being visibly wider than the downstream front leg.
  • As with any fixed valve, it can never become stuck to the deck nor can it spin.
  • The large net rises available plus the directional liquid flow make this an outstanding anti-fouling valve. It is widely used on anti-fouling SUPERFLUX® trays.
    • Using a large net rise ensures that large particles can freely pass through the deck openings.
    • There are no protrusions below the deck for any material to hang up on and for deposits.
    • The liquid push is strong enough to help solid material to be flushed downstream and toward the downcomer where it can exit off the tray deck.
