Product catalog summary

Overview
The Sentry® manifold switching valve assembly is designed for sequencing multiple samples to a single analyzer. It is compatible with the Sentry Sample Sequencer® 5 and other control systems, available in four- or eight-port configurations, and is easy to install and configure.

Models
Two models are available: L1 (Four-port) and L2 (Eight-port).

Benefits

Ensures representative samples from every line with continuous sample flow.
Prevents cross-flow contamination with a block and bleed feature.
Minimizes purge time and eliminates dead legs.
Available in 1/8-inch and 1/4-inch valve sizes.

Features

No cross-flow contamination due to valve block and bleed feature.
Continuous sample flow in all lines.
All wetted surfaces are continuously swept with high-velocity samples.
Minimal purge time and no dead legs.

Gas Liquid & Slurry Solid & Powder SENTRY MANIFOLD SWITCHING VALVE Sample Conditioning Automation Steam & Water The patented Sentry® manifold switching valve assembly is designed specifically for use in sequencing multiple samples to a single analyzer. It works in conjunction with the Sentry Sample Sequencer® 5 or with other control systems. It is available as either a four- or eight-port configuration and is easy to install and configure. MODELS L1 (Four-port) | L2 (Eight-port) BENEFITS To assure a representative sample from every line, all samples flow continuously, whether in or out of sequence. Normally the common sample port is closed and the sample goes through the drain port. When a solenoid coil is energized, that particular sample goes through the common port and exits to the analyzer (see figure, right). The manifold design provides flow in both directions from the open valve. This eliminates dead legs, assures complete purging of the old sample, and minimizes purge time between samples. Additionally, sample integrity is maintained with a block and bleed feature on each valve that prevents any possibility of cross-flow contamination. FEATURES No cross-flow contamination with valve block and bleed feature Continuous sample flow in all lines All wetted surfaces continuously swept with high velocity sample Manufactured under one or more U. S. patents: 5,469,751 Minimal purge time, no dead legs
