Swagelok the GB Ball Valve

Application for the GB Ball Valves

Swagelok GB ball valve, the full-bore, bidirectional flow–capable ball valve. The valve is engineered to provide flow rates at a working pressure of 6000 psig while simplifying installation, minimizing rework requirements, and delivering the reliable shutoff performance needed to keep workers safe and systems operating efficiently in a variety of demanding applications. The ball valve can be widely deployed as a general-purpose ball valve.


The series ball valve is available in a variety of alloy materials such as 6-Moly, Alloy 2507, and Alloy C-276, as well as materials selected in accordance with NACE MR0175 for sour gas applicationsThe valve also complies with ASME B31.1 and B31.3 standards for power and process piping systems.

  • Working pressures up to 6000 psig (413 bar) with temperatures from –40 to 250˚F (–40 to 121˚C)
  • Swagelok® tube fitting end connections in fractional (3/8 in. to 1 in.) and metric (12 mm to 25 mm), female pipe end connections in fractional (3/8 in. to 1 in.)
  • Corrosion-resistant body materials: 316/316L, Alloy 2507, 6-Moly, Alloy 625, Alloy 825, Alloy C-276
  • Mechanically locked end screw design (patent pending) provides increased safety
  • Optional NACE MR0175/ISO 15156 for sour gas


The Swagelok GB series ball valve can be utilized as a general-purpose ball valve. Applications for the valve include:

  • Fire suppression systems
  • Oil & Gas Industry
  • Isolation for compressed natural gas (CNG) infrastructure
  • Process and instrument isolation
  • High flow, high pressure liquid and gas
  • Hydraulic, injection and control packages
  • Highly corrosive applications


Designed to suit the needs of a wide range of high-flow application in diverse industries and environment.
