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 ).
