Design Range

Size Range:

  • DN 50 to 300
  • NPS 2 to 12

Pressure Class Range: 150 to 2500

Seating Material: Metal-to-metal

Features and Benefits

  • Broad application versatility due to robust design, making valve well-suited for isolation in compressor, pump, meter, water or gas injection system applications
  • Improved plant and personnel safety assured by double-isolation design
  • Installation ease from compact design with the same face-to-face dimension as a single valve
  • Greater process control via proven Dynamic Balance® pressure-balanced and sealing technology to prevent unequal pressure above/below the plug
  • Low lifecycle costs compared to two single valves
