V500: THE EROSION FIGHTER
Reverse Flow Advantage
For erosive applications, the
recommended flow direction for the
V500 valve is with the shaft upstream.
High velocity flow is isolated in the port
or outlet area. Here the seat ring and
retainer can be protected by utilizing
erosion-resistant materials and can be
easily maintained.
Long-Life, Bi-Directional Seating
Both sides of the seat ring have a
shutoff surface, allowing the ring to be
flipped over to extend operating life.
The seat ring self-centers, self-laps,
and dynamically aligns with the plug,
achieving bi-directional ANSI Class IV
shutoff.
Reduce Maintenance
The image to the left depicts computational
fluid dynamics, showing where high velocity
flows occur in the V500 valve at 45 degrees
of travel. A closeup view of the seating
surface is shown above. The reversible seat
ring in the V500 valve protects against the
toughest erosive flows. It provides back-up
sealing if needed.
