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
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.
