Manifold sample valve assures continuously flowing, contemporary samples in conjunction with the Sentry Sample Sequencer 5. The unique manifold design provides flow in two directions from the open valve, eliminating dead legs and minimizing purge time following stream switching. Sample cross contamination is prevented by using 3-way solenoid valves which separate the drains.

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.
