Abstract
A valve includes a cage having at least one fluid inlet proximate a first end of the cage and a fluid outlet proximate a second end of the cage. The valve also includes a spool configured to move axially within the cage between an open position in which the spool enables fluid flow from the at least one fluid inlet to the fluid outlet and a closed position in which the spool blocks fluid flow from the at least one fluid inlet to the fluid outlet. The valve further includes an annular seal supported within an annular groove formed in one of the cage or the spool. The annular seal is configured to seal a radial gap between the cage and the spool while the spool is in the closed position and is positioned between the first end of the cage and the at least one fluid inlet along an axial axis of the valve to block fluid flow from the at least one fluid inlet to the fluid outlet while the spool is in the closed position.
