Dresser/Cooper Gate 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.
