Swagelok GB Series Ball Valve Brings Added Safety, Simplified Installation to High-Flow Applications

June 19, 2020
Versatile, full-flow valve is designed for extended operation in harsh environments at a working pressure of 6000 psig.

Swagelok releases the full-bore, bidirectional flow–capable Swagelok GB series ball valve. The new valve is engineered to provide high flow rates at a working pressure of 6000 psig (413 bar) while simplifying installation, minimizing rework requirements and delivering reliable shutoff performance needed to keep workers safe and systems operating efficiently in a variety of demanding applications. 

The Swagelok GB series ball valve can be widely deployed as a general-purpose ball valve. Ideal applications for the valve include hydraulic, injection and fire suppression systems in the oil and gas industry; isolation for compressed natural gas (CNG) vehicle infrastructure; and isolation in highly corrosive alkylation operations in the chemical and petrochemical industry. When combined with Swagelok’s broad range of tube fittings, tubing, and instrument valves, the new ball valve enables customers to build a complete 6000 psig-rated fluid system with tubing diameters up to one inch using all Swagelok components.

For engineering, procurement and construction (EPC) companies and fluid system package vendors, the Swagelok GB series ball valve reduces the time and cost required to install and verify the performance of components installed in high-flow industrial applications.

The valve is designed for quick, easy setup with bidirectional flow eliminating concerns about backwards installations. Integral Swagelok end connections that range in size from 3/8 in. to 1 in. simplify system design and minimize labor and component requirements. The potential for leaks or costly rework after initial installation is reduced through 100% assembly testing that ensures Swagelok GB series ball valves meet specifications out of the box. Body seal performance is validated through hydrostatic system proof testing up to 1.5 times the maximum rated pressure.

The valve is built to allow simple customization, featuring a bolt pattern that can be used as an installation point for an optional lockout handle or panel mount as well as a bracket compatible with an ISO 5211 pneumatic actuator.

The valve features a patent-pending, mechanically locked end screw design that reduces risk of accidental disassembly or leakage. A leak-tight stem seal design with a blowout-proof stem provides additional reliability. To reduce corrosion in harsh environments, the Swagelok GB 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 applications. The valve also complies with ASME B31.1 and B31.3 standards for power and process piping systems.
