Anderson Greenwood and Crosby are the world's premier manufacturers of pressure relief valves, tank blanketing products and instrumentation valves and manifolds.
Anderson Greenwood began as an airplane manufacturer in 1947, when the first AG-14 plane was produced. The Korean War stopped airplane production, and Anderson Greenwood utilized its engineering capabilities in subcontracting work for various airframe companies. They eventually set aside a valve design group to develop new valve ideas.
In 1954, their research and inventiveness resulted in the development of the first soft-seated safety-relief valves and hand valves. By 1957, Anderson Greenwood had developed the first line of pilot operated valves, the Model 23. Since then, Anderson Greenwood has become the premier pilot-operated safety relief valve company in the world.
