Abstract
Certain aspects and features of the disclosure relate to a valve device for use in a wellbore. In one example, the valve device includes a body containing swell fluid, a swellable elastomer, and a piston. The swell fluid can contact the swellable elastomer, causing the swellable elastomer to swell. The swellable elastomer can swell and contact the piston. The swellable elastomer can move the piston from a first position to a second position. In the second position, the piston can open, close, or restrict one or more flow paths through the valve device.
