Cooper Alloy
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.

Valves Accesories
Jacketed Valves: (Bolt-on or Full-welded Type) Valves can be equipped with a fabricated body jacket through which steam or other heating media can be circulated. This keeps the valve functioning while handling heavy, viscous fluids.
Stainless Steel Add Shields: Valves installed in an inverted position can be furnished with acid shields to prevent corrosive or hazardous media from affecting surrounding work areas.
Gear Operators: Gate and globe valves can be equipped with bevel gear or chain wheel operators.
Extended Bonnets or Stems: Gate and globe valves can be fitted with a bonnet extension for cryogenic service, or extended stems to permit manual operation when the valve is located out of normal reach.
Fugitive Emmissions: Cooper valves can be equipped to prevent the escape of fugitive emmissions.
Other Options: Cooper has the capability of providing a wide range of services beyond those shown in this brochure. These include corrosion evaluation, vacuum test, helium test, special tagging and special hydrostatic testing. Consult factory for assistance.
