What is proposed is a valve, in particular an injection valve, having a valve seat and a valve needle extending principally along a closure direction, wherein the valve seat has a valve seat surface, wherein a valve closure body is attached to an end of the valve needle oriented toward the valve seat, wherein the valve closure body can be moved between an open position and a closed position, wherein, in the closed position, the valve closure body forms a sealing seat with the valve seat surface, the valve closure body having a higher core hardness and/or surface hardness than the valve seat surface. |
