Anderson Greenwood Instrumentation
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. The concept of manifolding three or more valves together in one body to use in connecting flow meters to the process was realized by obtaining a license from the inventor. This revolutionized the installation of differential pressure instruments.

Today, Anderson Greenwood is regarded as the worldwide technology leader in research, design and manufacture of high quality, high performance valve products. This reputation has been earned on the basis of care and commitment to our valued customers.
