Valve devices for selectively controlling fluid flow through multiple converging paths are described. An example valve device comprises a housing defining first and second inlet paths, an outlet path, a junction in fluid communication with the first and second inlet paths and the outlet path, and first and second plunger cavities. A first movable plunger is disposed in the first plunger cavity and a second movable plunger is disposed in the second plunger cavity. A control member is slidably attached to the housing and is movable between a first, proximal position with the first plunger in a first position to impede fluid flow through the first inlet path and the second plunger is in a second position, and a second, distal position with the first plunger in a second position and the second plunger in a first position to impede fluid flow through the second inlet path.
