Duff & MacIntosh introduces Sentry's patented manifold sample valves, specifically designed for use in sequencing multiple samples to a single analyzer.

These manifold sample valves work in conjunction with Sentry's Sample Sequencer IV or with other control systems. Available in either a 4-valve or 8- valve configuration, the Sentry’s sample valves are easy to install and configure.

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.

The manifold design of these valves provides additional flow in both directions from the open valve, eliminating dead legs and assuring complete purging of the old sample.Purge time between samples after stream switching is minimized.

Sample integrity is complete with a block and bleed feature on each of the valves preventing any possibility of cross flow contamination.
