A homogenization valve includes a housing and stacked valve members within the housing. The valve members have central holes therethrough defining a high pressure volume. Each valve member includes a valve seat defining, with a valve surface, gaps through which fluid is expressed radially from an inside high pressure volume to the outer low pressure volume. An actuator closes one end of the central volume and acts on the valve members to control the width of the gaps. A pressure barrier is positioned within the central volume to reduce the force from the central volume acting on the actuator.
