The Taper Plug valve is manufactured
in sizes 1/2 inch thru 12 inch and is used on a wide
variety of liquid, gaseous, and slurry services.
The taperd plug is held firmly into
its tapered seat, but can be so adjusted that complete
leak tightness is achieved together with smooth valve
operation. The tapered seat surfaces of the plug and
body are not exposed to the line fluid when the valve
is in the open position, so that the effects of corrosion
and erosion are confined to the less important parts
of the valve. Also since there is a straight flowpath
through the valve, there is very little resistance to
flow, and pressure loss is minimized.
Super LoMu Treatment
All Carbon Steel taper plug valves,
sizes 1-1/2 inch and above, have plugs with Flowserve
Audco Supor LoMu treatment. In this unique process,
low friction PTFE is incorporated in the surface structure
of the valve plug metal. This gives easier operation
and enhanced resistance to taper lock over thousands
of operations or many years of service.

The Flowserve Nordstrom Dynamic Balance
valve is the premier Nordstrom plug valve which incorporates
proven features and user benefits from over sixty years
of experience in endless valve applications and design
technology.
A pressure-balanced plug assures predictable
torque even under high pressure differential, vibration
and thermal cycling. Pressure-energized stem seals eliminate
external adjustments and the stem and cover weatherseal
provides superior corrosion resistance in hostile environments.
The Dynamic Balance plug valve is
available in the broadest range of sizes, pressure classes,
and materials of construction of any Nordstrom Audco
product. Dynamic Balance valves are available in sizes
from 1 to 30 in ANSI pressure classes from 150 to 2500,
and in sizes 2-1/16 to 4-1/16 in API pressure classes
3000 and 5000.

The Flowserve Super Nordstrom plug
valve carries on the Nordstrom tradition of valving
excellence. Complementing the broad line of Dynamic
Balance plug valves, the Super Nordstrom valve offers
dependable, bubble-tight shut-off and predictable torque
in an economical line of valves in a smaller size range
(1/2 through 4) for low to medium pressure (ANSI classes
150, 300 and 600).
The Super Nordstrom design features
a stainless steel spring that is compressed between
the small end of the plug and body. This applies a constant
force to the plug, tending to lift it out of the taper.
This movement of the plug, however, is limited by stainless
steel controlled-dimension washers located between the
large end of the plug and cover. The "controlled-balance"
effect is maintained by the spring pressure at the small
end of the plug and the controlled dimension washers
at the large end.
Extensive testing - not to mention
years of experience with Dynamic Balance plug valves
- has shown that this precisely controlled vertical
lifting of the plug eliminates wedging of the plug in
the body taper without affecting tight shut-off. The
plug is permanently adjusted at plant assembly by selection
of the proper washers - thereby eliminating the need
for field readjustment.

Flowserve invented the non-lubricated
plug valve for the most corrosive and difficult chemical
services where drop-tight shutoff is an absolute requirement.
Nearly 50 years later there are many imitators but no
substitute for the quality and reliability, versatility
and value you receive with Sleeveline valves.
Durco valves offer the process industries
widest range of non-lubricated plug valve models, materials,
and configurations. This provides customers the flexibility
to specify Sleeveline valves to meet virtually all their
applications needs.
Flowserve has the answer to your corrosion-resistant,
quarter-turn valving needs-whethe for on-off or modulating
control.
Features:
Double-D
Plug Stem is compatible with most standard actuation
equipment.
Tapered
Plug assures reduced turning torque and in-line seal
adjustment.
