Abstract
An apparatus for controlling a fluid flow in a borehole may include a tool body that retrieves a fluid sample from a subsurface formation. The tool body has a fluid conduit having an inlet for receiving the fluid sample and an outlet for conveying the fluid sample to a selected location. A mandrel selectively blocks flow across the fluid conduit; and a seal disposed on the mandrel includes at least one chevron seal element that cooperates with the mandrel to selectively block flow across the fluid conduit.
