# Dual active selector valve

## Abstract

A dual active selector valve is set forth. In the preferred and illustrated embodiment, a flange supporting a manifold body is attached to a pressure vessel. The passage through the flange has a selected diameter and the manifold body opens out to a larger diameter, sufficient to enable two valves to be connected side by side, having inlet passages equal in diameter to about one half the selected diameter. A rotatable conduit member is mounted within the manifold body having a centrally located pin for rotation, the rotatable portion incorporating separate flow passages selectively connecting to one of the two alternately deployed valves, and also supporting a valve closure plate to plug the passageway into the valve not being used.
