Swagelok^® Gas Distribution Systems

Swagelok standard gas distribution panels come fully assembled and tested. They are easy to order from our application guide as single part numbers, minimizing the time your engineers spend on specification and procurement of new systems.

Swagelok modular panels feature minimal threaded connections to reduce potential leak points, and they are intuitively labeled to promote safe, simple use, and maintenance, and are backed by the Swagelok Limited Lifetime Warranty.

Swagelok gas distribution systems are built around one or a series of pressure regulation steps, and may include four subsystems:

• Swagelok^® source inlet (SSI)
• Swagelok^® gas panel (SGP)
• Swagelok^® changeover (SCO)
• Swagelok^® point-of-use (SPU)

Swagelok^® Source Inlet (SSI)

The source inlet establishes a connection between the high-pressure gas source and the distribution system. It is important the inlet is built with appropriate cylinder connections, hoses, tubing, filters, and vent, purge, and relief functions to ensure that gas can be safely fed into the primary gas pressure control or automatic changeover. For a single gas cylinder, the assembly can be as simple as a hose and connector, while multiple cylinders may require a manifold incorporating many hoses and valves. Swagelok offers highly configurable options to purge or vent gases when changing bottles, always ensuring operator safety, as well as an available option to vent individual lines to maximize uptime.

Swagelok advisors will ensure all componentry is included and correctly specified with minimal connection points, hoses that do not drop to the ground, and properly supported components. Additionally, we can advise when certain gases may require the use of special hoses.

Swagelok^® Gas Panel (SGP)

The SGP completes the first pressure reduction of the source gas and ensures it is delivered at the correct flow rate to the next stage of the system. Pressure reduction is accomplished in either one stage with a single pressure regulator or two stages through a dual pressure regulator arrangement.

Swagelok offers modular panels that are easy to service as any part can be detached via a Swagelok connection, so the panel never needs to be removed, as well as options implemented around the regulator and valves for color-coding if required for your site. Swagelok can also help you understand where a two-stage regulator is required.

Swagelok^® Changeover (SCO)

The automatic changeover system seamlessly switches from one gas source to another to ensure an uninterrupted supply. This is accomplished through staggered set points of two pressure regulators, allowing the system to continue to operate as the primary gas source is changed. The changeover station allows for specified changeover set points to reduce wasted gas left in cylinders.

Swagelok offers more assurance the changeover point remains constant, as well as optional line regulation if your system incorporates a point of use regulator downstream—this can eliminate the additional cost of a regulator on the SCO. Swagelok specialists can help your team better understand system functionality, troubleshoot, and maintain operations.

Swagelok^® Point-of-Use (SPU)

The point-of-use provides the critical last stage of pressure control prior to the gas being used. These typically have a pressure regulator, gauge, and isolation valve. Point-of-use systems offer a convenient and accurate method of adjusting pressure to meet test bench or equipment needs.

Swagelok offers standardization and consistent operation at the point-of-use; flat plate, bottom mount, top mount, and wall mount options; and a compact design. A Swagelok specialist can show you hidden savings, like how a single-stage SGP can be used to minimize cost where varying line pressure between the SGP and SPU is acceptable.
