<p>A valve (100c,100d,100e) comprises a valve body (108c,108d,108e) which includes a sealing surface (126c,126d,126e); a valve core (102c,102d,102e) disposed in said valve body (108c,108d,108e); a self-aligning valve seat member (200c,200d,200e) pivotably engaged with said valve core (102c,102d,102e), said valve core (102c,102d,102e) being slidable generally within said valve body (108c,108d,108e) to an open position wherein a sealing surface (202c,202d,202e) of said self-aligning valve seat member (200c,200d,200e) disengages from said sealing surface (126c,126d,126e) of said valve body (108c,108d,108e) thereby allowing fluid flow through said valve (100c,100d,100e).
