A valve within a valve block for an ABS brake system, comprising an elongated valve seat 201 with first and second inlets 206, 209 and an outlet 211, a pressure regulation spring 202, a piston 203 with radial channels 210, a ball 204 placed against a cone 224, and a suction spring 205 supported by a spring pot 206, wherein the piston is limited by a retaining ring 207 on one side, and by chamfers s on the other, and the radial channels are capable of fully aligning with the second inlet. When pressure increases at the second inlet, the piston rises and reduces the volume of fluid transferred from the second inlet to the outlet. The retaining ring may be placed on a groove g on the inner side of the valve seat. Preferably, the radial channels are connected to additional hydraulic lines to ensure a failsafe mechanism.
