A high pressure valve of a common rail for an internal combustion engine of an automotive vehicle, said valve comprising:a body and a needle,the body being provided with a bore extending along a longitudinal axis, the fuel exit forming a needle seat,the needle extending from a head to a tip, and being configured to reciprocate in the bore along said longitudinal axis from a closed position to an open position,a coil and an armature arranged to be controlled by the coil such that, in the closed position, the tip of the needle closes the fuel exit, and, in the open position, the tip of the needle is spaced apart from the fuel exit to open the fuel exit,a housing (30) surrounding at least partially the coil,wherein the housing (30) is made of an elastomer matrix with magnetic particles.
