PROVALVE® valve
A fixed valve that offers the wide operating range of conventional valve trays, but with no moving parts.


PROVALVE® fixed valve


  • Higher capacity than full-size
    valve trays
  • Maximum opening size for
    maximum fouling resistance
    and free passage
  • Longest up time between
    shutdowns
  • Fixed opening so valve
    cannot stick shut
  • High weepage resistance
    for a wide operating range
  • Easy to clean; less downtime
  • Rugged, durable construction
    for long tray life
  • FRI tested
  • Patented

 

The PROVALVE valve offers the wide operating range of conventional valve trays, but with no moving parts. The valve design prevents valve leg or deck wear and eliminates the potential for popped, fouled, or stuck valves.

  • The tapered cover imparts a forward lateral push to the liquid across the tray, allows a large open area, and directs and deflects the vapor.
  • The result is uniform liquid and vapor distribution across the entire tray with a low, even spray height across the deck. This increases the tray’s efficiency, prevents liquid backflow, suppresses jet flooding, and permits operating at greater vapor rates.
  • The cleansing action from the liquid push protects the tray deck from fouling.
  • In addition, the sheltered valve design allows a large open area that promotes lower pressure drop and protects against vapor surges.
