Design Range

Size Range:

  • DN 25 to 750
  • NPS 1 to 30

Pressure Class Range: Class 150 to 2500

Seating Material: Metal-to-metal

Features & Benefits

• Increased uptime due to pressure-balanced plug, which ensures predictable torque, even under high differential, vibration and thermal cycling
• Reliable performance in hostile environments provided by the anti-friction coating weather seal that provides superior corrosion resistance
• Reduced downtime with pressure-energized stem seals
• Broadest range of sizes, pressure classes and materials
• Reliable operation enabled by the Sealdport sealant grooving system, designed to give complete distribution of pressurized sealant to seating surfaces
