ABSTRACT:
A valve includes a valve body (100) disposable within a chamber (103) of a housing (101) and capable of being fluidly sealed with respect to the housing (101) when the valve is closed. At least one radial passage (117) is disposed in the valve body (100). At least one axial passage (119) is disposed in the valve body (100) in fluid communication with the at least one radial passage (117). When the valve at least partially opens, a fluid path opens between the valve body (100) and the housing (101), which fluid path (301) in is fluid communication with the at least one radial passage (117), and fluid from within the housing (101) is capable of passing out of the at least one axial passage (119).
