Copeland
Power
Valve
Series
valve contains most of the same internal
components and design principles still
used today. The coatings are a little better
and now there is a 4 year, Zero Leakage
limited warrantee but Copeland stood
behind its products then and we still do
now!
Copeland was
coating ball valve
components for
some of the new
start-up companies
interested in
developing severe
service ball valves.
Fisher, a leading
control valve
company, heard of
Copeland's new
series of products
and an agreement
was made to
manufacture
Copeland's valves
and sell them
through the Fisher
network of sales
agents.
The original
product was mass
produced and
became a big
success,
encouraging
look-alikes from
several companies.
However, Copeland
never stopped
developing the
series and now
offers the most
advance product on
the market, all
based upon the
same principles
that the Fisher
company found so
attractive:
Simplicity,
functionality and
price.
There are already
several new
models yet to be
introduced,
however, like their
predicesors, the
quality and
precision
craftsmanship that
made Copeland
famous will still be
there.

customers in mind. In China, butt weld end connections are
the norm and Copeland's coating and delta ring body seal
has improved to the point that this valve is more reliable and
more cost effective than ever before. The valve comes in butt
weld, socket weld and other end connections.
Valve, is still sold today. The cost of
manufacture of the original Power Valve
was reduced by using bar stock and a
preformed mounting flange. However, the
internals and the operating principles of the
valve never changed. There are still
advantages to this design and the old
adage, "if it ain't broke, don't fix it." makes it
a popular choice for many power plants
and engineering companies.
Although the components are made in the USA, the color red
is in honor of our neightbors to the East who encourage the
development of the new two piece design.
Reduced bore ball valves for high pressure steam applications. Features carbide sealing areas, live-loaded
graphite packing and a forged body. Available in ANSI Class 900, 1500, 3000, 3200 and 4500 ratings. Sizes range
from 1/2" to 4".
Key Benefits
Long-Term Shutoff Integrity: Externally positioned guide bearings helps maintain precise ball-to-seat alignment.
Extended Packing Life: Packing gland followers uniformly energizes the live-loaded Grafoil® packing to extend
packing service life. Avoids the side loading common to two-bolt and four-bolt packing followers.
Extra Heavy Duty Blow-out Protection: High-strength Inconel® 718 pins help ensure shaft retention.
High-Pressure Capability: Forged WC9 chrome moly (F22) or carbon steel (A105) body provides superior
pressure-retaining integrity in high-pressure power plant applications. All other ANSI B16.34 materials available as
well.
Cost-Saving Operation: Shutoff to MSS-SP61 specifications avoids wasteful steam loss due to excessive valve
leakage. Valves are also shipped with a Zero Leakage and 4 year limited warrantee.
Superior Wear Resistance: Ball and seat surfaces have been hardfaced with thermally-sprayed chrome carbide for
extreme resistance to abrasion. Inconel 718 internals add to operating integrity.
Lighter, Easier to Handle Design: Body offers a significant size and weight reduction over other designs. Proves
easier to handle.
