Described herein is an improved externally mounted pressure relief valve that is especially adapted for rail tank cars or other large closed containers that contain or transport fluids, including liquids and gases. The pressure relief valve comprises a plurality of spring assemblies, and each spring assembly contains a pre-determined number of spring leaves. Each spring assembly is coiled upon a corresponding spring drum, and each spring drum is penetrated by a corresponding spring drum bolt. The spring assemblies are preferably aligned in at least two horizontal planes that are parallel to each other and normal to the vertical length of a spring block. The spring block and sealing disk are mounted vertically over the valve seat and within the confines of vertically extending spring brackets.
