In 2011, DeZURIK acquired APCO Willamette - a leading water and wastewater brand boasting a history of innovation dating back to 1895, when it introduced the world to the company’s first automatic pump primers. The primers were so successful that they became the foundation for APCO’s rich heritage of innovation. The next engineering and manufacturing marvels were APCO’s Air Valves and full Check Valve product line, introduced in 1957. Today, the APCO brand is synonymous with specialty valves built to customer specifications up to 120-inches in diameter. With renowned technology in air valves and check valves, APCO products are a perfect addition to DeZURIK’s vast line.
