  1. Tapón excéntrico

  2. Tapón excéntrico

  3. Tapón excéntrico

  4. Tapón excéntrico VENTAJAS Buen cierre Alta capacidad de flujo (Cv) Amplia rangeabilidad (160:1) Opera bien en productos con contenido de fibras o muy viscosos Excelente para vapor saturado Disponible en puertos reducidos DESVENTAJAS Chocan con caídas de presión menores que las válvulas de globo No es posible obtener sello Clase V

  5. Eccentric Plug Advantages • High Cv s and good rangeability • Good for high drops (1440 psi) • Excellent for saturated steam • Reduced trims available (70% and 40%)

  6. Eccentric Plug Disadvantages • Class V shutoff unavailable • Limited body materials (CS and 316 SS) • Chokes at lower pressure drops than globe valves

  7. How good is your style selection expertise?

  8. Example 1 Water @ 100o F P1 = 480 psia P2 = 450 psia Air-to-open, fail-closed 10-inch sch. 40 pipe Flow = 9100 gpm Throttling Max. P = 50 psi Which valve style would you select?

  9. Valdisk Valve (High-performance Butterfly)

  10. Example 2 Water @ 100o F P1 = 800 psia P2 = 350 psia Air-to-open, fail-open 2-inch sch. 40 pipe Flow = 250 gpm Throttling Max. P = 785 psi Which valve style would you select?

  11. Mark One Valve (High-performance Globe)

  12. Example 3 4 - 6% brown stock @ 200o F P1 = 60 psia P2 = 48 psia Air-to-open, fail-closed 8-inch sch. 40 pipe Flow = 5000 gpm Throttling, 316 SS body Max. P = 45 psi Line size valve Which valve style would you select?

  13. ShearStream Valve (Segmented Ball)

  14. Example 4 Steam @ 500o F P1 = 760 psia P2 = 245 psia Air-to-close, fail-open 6-inch sch. 40 pipe Flow = 100,000 lb/hr Throttling, 316 SS body Max. P = 745 psi SPL = 106 dBA w/o insulation Which valve style would you select?

  15. MegaStream Valve (One-stage with insulation factor)

  16. Example 5 Natural gas @ 200o F P1 = 80 psia P2 = 75 psia Air-to-open, fail-closed 8-inch sch. 40 pipe Flow = 1,100,000 scfh Throttling, carbon steel body Max. P = 80 psi Min. valve size is 1 size < line size Which valve style would you select?

  17. Valdisk 150 Valve (High-performance Butterfly)

  18. Example 6 Water @ 100o F P1 = 450 psia P2 = 90 psia Air-to-open, fail-closed 4-inch sch. 40 pipe Flow = 600 gpm Throttling, carbon steel body Max. P = 80 psi Sigma required = 1.15 to 1.25 Which valve style would you select?

  19. ChannelStream Valve (Two-stage Trim)

  20. Example 7 Saturated steam @ 450o F P1 = 225 psia P2 = 200 psia Air-to-open, fail-closed 8-inch sch. 40 pipe Flow = 50,000 lb/hr Throttling, 316 SS body Max. P = 210 psi Line size valve Which valve style would you select?

  21. MaxFlo Valve (Eccentric Plug)

  22. Example 8 Saturated steam @ 450o F P1 = 225 psia P2 = 200 psia Air-to-open, fail-closed 8-inch sch. 40 pipe Flow = 50,000 lb/hr Throttling, 316 SS body Max. P = 210 psi Cv required is very small Which valve style would you select?

  23. Mark One-X Expanded Outlet Valve (6x4-inch or 8x4-inch)

  24. Don’t Forget MaxFlo, Valdisk 150, and Mark One-X valves can be applied to many valve applications

  25. So, “Which control valve style is best?” The choice is yours!
