Abstract
A shuttle valve has a valve body including a first valve seat defining a first fluid inlet, a second valve seat defining a second fluid inlet, and a center portion that is connected to the valve seats, the center portion defining a fluid outlet and a bore. A moveable member is moveable within the bore between a first position against the first valve seat and a second position against the second valve seat to control the flow of fluid from either of the first or second inlet to the outlet. The moveable member may be configured to have a unitary construction formed of a single component, by which a unitary shell defines a substantially hollow interior. The moveable member has a hollow interior and a weep hole for equalizing pressure between the hollow interior and exterior of the moveable member.
