Adams Valves is headquartered in Herne, Germany and it has stood at the forefront of advanced valve technology since its invention of the triple-eccentric valve in 1960. In 1966 Adams developed the laminated metal seal ring which is used in most triple-eccentric valves or triple offset valves today. This revolutionary improvement in valve technology has set new standards for seal life, tightness and temperature range. For five decades, with three manufacturing facilities, 25 global offices, agents, and many more sales representatives around the world, Adams Valves has enjoyed an industry reputation for its superior performance, quality and reliability.

Adams Valves, Inc USA is an independent subsidiary of its German parent company and the only Adams valve manufacturing facility in North America located in Houston, Texas.
