APCO/Valve and Primer Corporation was Established in 1895.
In the beginning, the firm's name was AUTOMATIC PRIMER COMPANY, or in an abbreviated b....APCO.
As years passed, the trade name APCO steadily gained wider recognition, by Design Engineers, than the true corporate name. Hence, the valves were commonly referred to and specified as APCO VALVES.
AUTOMATIC PUMP PRIMERS were the first products introduced. These were successfully marketed and became the foundation on which to build. Next introduced were AIR VALVES and today APCO's the leading producer of the most complete line of AIR VALVES in the world.
APCO AIR VALVES are used on pumps and pipelines in Power Plants, Utilities, Municipalities and Industrial Plants of all types. APCO has furnished AIR VALVES to the ARMY, NAVY, AIR FORCE, COAST GUARD and on many critical installations, including MISSILE SITES and NUCLEAR SUBMARINES.
In 1957, VALVE AND PRIMER CORPORATION introduced it's first check valve line. Since then, there has been a steady introduction of distinctly different APCO Check Valves, Including:
