Features and Benefits:

• Balanced 4-Seat Construction
  Unlike 2-seated diverter valves, the 509F series has 4 seats (5 seats in bottom entry valves) for positive shut-off in the closed position. This true multiport function can reduce the number of valves required in a process system and gives engineers greater design flexibility

• Trunnion Mounted Ball (1 1/2" - 4")
  Stem/ball isolation prevents side loading and wear of downstream seats, improving performance and service life

• ISO 5211 Mounting Pad
  Standard mounting pad dimensions make it easy to assemble electric or pneumatic actuators
• High-Cycle, Live Loaded Stem Packing
  Dynamic loading on stem packing ensures a tight seal through varying pressure and temperature conditions, extending service life and reducing maintenance costs

• Blow-Out-Proof Stem
  Stem is bottom loaded to prevent removal when valve is in service

• Full Port Design
  Full port construction improves flow characteristics for greater process efficiencies

• Multi-Position Lever Handle
  The lever handle can be positioned in two (1/2"-2") or four (3"-4") different orientations for greater piping flexibilit

• 90° or 180° Actuation
  Stop plates are available for both 90° and 180° actuation

Operating / Test Conditions:

• Temperature Range (CF Seats): -20° to 420° F

• Maximum Working Pressure: 
  ANSI 150: 275 PSI WOG (1/2" - 4")
  ANSI 300: 720 PSI WOG (1/2" - 2")
  ANSI 300: 600 PSI WOG (3" - 4")
  

• All valves shell and seat tested to ANSI/ASME B16.34 and API 598

• All materials comply with applicable ASTM material specifications

• End connections: Flanged ends to ANSI B16.5

Options:

• 4- or 5-way construction with multiple flow patterns

• Available in standard port construction for applications where flow rates are not critical and greater economy is desired
