Everlasting Valve Company Inc.
Everlasting Valve Company was founded in 1906 by Patterson Allen Engineering, New Jersey, to manufacture and market steam boiler blowdown valves. During the 1960s, the distinctive features of the Everlasting Rotating Disc Valve were incorporated into our process valves, bulk material valves and diverter valves. Engineered for exceptional performance, longevity and value, our valves have replaced knife gates, pinch valves, slide gates, rotary air lock, double dump, ball and plug valves. Today, Everlasting Valve continues to set the industry standard as the valve of choice in severe service applications around the world.
