A pressure control valve for a fuel tank with a spring-loaded valve body is intended to combine a maximum sealing effect with an unobstructed and reliable response. This is achieved in that the valve body comprises a foot part and a plate, the foot part being guided displaceably in the valve housing in the axis of symmetry, the plate having, in a staggered manner, a first groove and a second groove for holding a first sealing ring and a second sealing ring, the two sealing rings bearing against the sealing surface when the valve is closed and being flowed around in series when the valve is open.
