The SchuF Maniflow Selector Valves (MSV) - a multiport selector valve type - is used in oil fields and other Oil and Gas applications for the testing and analysis of oil from two or more production wells. Previously this had to be achieved with a manifold with extensive piping and multiple valves.
There are normally numerous production inlets, one test outlet, one main outlet and a selector mechanism.
The crude flow from any of the incoming wells can be diverted via the funnel like selector to the test outlet. The remaining crude is "manifolded" from the other inlets and exits directly via the main outlet.
