About Everlasting Valve Company, Inc.:

More than a century ago, Everlasting Valve was founded by Patterson Allen Engineering on the premise that an industrial valve should be even tougher than the applications for which it’s designed. With a focus on solving plant problems in some of the harshest industrial environments, the steam locomotive blowdown valve was developed and introduced in 1906. Over time, we continued to surge ahead of other valve manufacturers in terms of innovation—incorporating the unique rotating-disc design into our special-service valves as well—and constantly worked to refine and optimize our designs.
