Dresser/Cooper Globe Valves - Overview

Gate valves provide a straight-through passage for the flow of fluids. They are used where unobstructed flow and low pressure drops are needed. Although gate valves are not recommended for throttling service, they are suitable for on/off service in almost all media and are particularly useful in cryogenic or high temperature service.

Valve Accessories

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.
