It can be identified by the check stop nut and its metallic brass construction. This 130156 replacement thermostatic valve is not compatible with second-generation valves. Second-generation valves use a plastic polymer thermostatic element with a completely different design and size; therefore, this metallic brass version will not fit if your valve has the plastic version of the 130156.
