Grab Sample System Solutions

Grab Sample System Features

Swagelok offers two categories of grab sample systems to fill a variety of intended uses.

Grab Sample Modules (GSM)

The GSM uses pressure-rated sample cylinders to collect the sample from a positive pressure proves to prevent the sample from escaping.

Some operational and safety features:

• Rupture disc
• Relief valve
• Quick connects and hose to simplify and make operability safe
• Vent patch
• Geared valve assembly

A key feature of the GSM is the switching valve that directs flow. Using the Swagelok 40G series ball valve for this switching valve, configurations are available with either 2 or 3 valves. This allows for simultaneous control of fluid routing, reducing the number of sequencing steps required to draw a sample. The likelihood of errant sampling is reduced and a clear indication of sequencing is provided to the operator. This valve assembly is a standard on all GSM panels as well as fixed volume GSL panels.

Liquid-Only Sampling Systems (GSL)

A liquid-only sampling system (GSL) can be used in a number of liquid applications where the process fluid is not at risk of fractionating or evaporating when stored at atmospheric pressure. This allows the use of less expensive glass laboratory bottles to draw and store the sample. Using bottles also provides immediate feedback on the visual quality of the sample stream. Swagelok GSL systems use the same switching valve as a GSM system to provide simplified operation for complex tasks. The GSL systems also include Sentry Equipment's Model MVS to draw a sample into a bottle. The MVS is equipped with a spring-return handle to prevent unintentional dispensing. Swagelok GSL systems are designed around the use of Boston Round or media bottles but can accommodate other bottle geometries and materials. GSL systems are assembled with Swagelok tube fittings, avoiding the potential leak points of NPT fittings.
