Highest Quality: Since 1934, when the Cooper foundry developed the first successful technique to pour 304 stainless steel, we have used our experience and skill to continually refine and improve our product line. The production of highest quality stainless steel and exotic alloy valves today requires a combination of advanced design engineering, metallurgical science, technical know-how and rigid quality control. Cooper valve patterns have been continually refined, hand-in-hand with foundry technology to produce the finest quality castings-whether they be stainless steel or high alloy steel-available in today's market. All of these requirements are to be found in the day-to-day production of Cooper stainless steel and exotic alloy industrial valves.



Cooper manufactures a complete line of ball, gate, globe and check valves whether they are small diameter investment castings or large diameter sand castings, sizes 1/2" to 24", ANSI Class 150 thru 1500, in stainless or high alloy, or special design upon application. Cooper valves are manufactured to the applicable sections of ANSI and API standards and are in use in almost every corrosive application today.
