S23 Third Coupled Valve Configuration (D4)

PDFP&ID

The ability to purge the sample point ensures optimal retrieval of a representative liquid sample. The S23 type sampler with third coupled valve configuration provides a system purge and positive vent line shut off in addition to a fixed sample volume. This liquid sampler offers one-handle operation by multiple valves, allowing for sampling independent of the process conditions. These features provide sample accuracy, safety for the operator and zero emission.

Provide a new septum on your sample bottle. Insert the bottle, with cap and septum into the sleeve until the septum is pierced by the needles. Put the bottle retaining clip in place. The valve in the vent line is closed.

Turn the handle to the "bypass" position, allowing a continuous flow of liquid through the sample chamber to ensure representative sampling. This position can be held for any required time. The valve in the vent line is closed.

Turn the handle to the "sample" position allowing the product to flow into the sample bottle. The fixed volume chamber determines the amount of sample. The inert gas will assist the sample to flow into the bottle and will purge the sampler. This position can be held for any required time. The valve in the vent line is opened.

Turn the handle to the "off" position. Remove the bottle retaining clip and pull the bottle out from the sleeve. The septum reseals automatically. The valve in the vent line is closed.
