Cheminert stream 8 -Stream selection valves Videos While there are a variety of flowpaths available in the Valco selector line, Cheminert selectors generally function as basic stream selectors; a selected stream goes to a common outlet, as shown below. (Or, a single stream can be directed to a selected outlet.) ONLY > No PDFs detail ? examples Only > 8, 12, 16 streams > Click Image for > Video

VICI-Valco Stream selection with dead-ended streams Video 2,949 viewsAug 16, 2013 SD flowpath selectors select one of 4 to 16 dead-ended streams. This example illustrates a method for sampling non-pressurized containers which eliminates any possible effect from pressure differences among the containers, providing accurate and repeatable results. In step 1, a vacuum pump moves sample from the container selected by the SD valve to a 6 port sampling valve. In step 2, the 3 port valve blocks the vacuum flow through the sampling valve to allow the sample within the loop to equilibrate at atmospheric pressure. Then in step 3, the 6 port valve is switched, injecting the sample. All three valves can be automated with air or electric actuators for unattended operation

VICI -Valco Stream Continuous Flow to Individual Outlets Video
|
3,499 viewsAug 16, 2013 SF flowpath selectors select one of 4 to 16 streams, with the selected stream flowing from the valve outlet to a sample valve, pressure sensor, detector, column, etc., and each non-selected stream flowing to an individual dedicated outlet. This is the ideal solution when reactions or process streams with differing upstream pressures must be analyzed, and can also provide independent containment of toxic or noxious streams. An SF valve together with a 6 port sampling valve and pneumatic or electric actuators comprise a complete sampling system for the automated analysis of up to 16 sample points. In step 1, stream 4 is selected and the sample loop on the 6 port valve is loaded. In step 2, the 6 port valve is switched, injecting the sample. Step 3 advances the SF valve to stream 1, and the cycle is repeated.

VICI-Valco Sample Continuos Flow Trapping to Individual OutletsVideo
|
3,201 viewsAug 16, 2013 ST flowpath selectors are used for multi-trap, multi-column, or multi-sample operations. A typical application, shown here, is the collection of fractions at timed intervals for analysis at a later time. In step 1, the 6 port valve is in the collection/trapping mode, with loop 4 selected for filling. In step 2, the 6 port valve is in the analysis/desorption mode, with the contents of loop 4 going to the column. Valves can be ordered with matched loops already installed. Both valves can be supplied with pneumatic or electric actuators to automate these functions.

VICI -Valco Stream Selection example > Continuous Flow to Common Outlet Video
|
2,933 viewsAug 16, 2013’] SC flowpath selectors select one of 4 to 16 streams, with the selected stream flowing from the valve outlet to a sample valve, pressure sensor, detector, column, etc., and the non-selected streams flowing to a common outlet. This configuration is ideal for air quality monitoring; since the non-selected streams are continuously pulled through the valve, the most current sample will be provided as each point is selected for analysis. In step 1, stream 1 is selected and the sample loop on the 6 port valve is loaded. In step 2, the 6 port valve is switched, injecting the sample. Step 3 advances the SC valve to Stream 2, and the cycle is repeated.
