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.
Everlasting Valves are built using advanced computerized and robotic equipment, operated by our highly skilled and trained technicians. Every valve is assembled and tested in our ISO 9001:2008 certified facility in South Plainfield, New Jersey, U.S.A.
