Power valves for
high-pressure steam to 4500 psi: 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 GrafoilŪ 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 InconelŪ 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.

Valves for mining
applications: Mining
applications often introduce their own set of conditions that are,
oftentimes, unique to their industry. Special coatings, design
features and
materials used in mining valves are the norm rather than the
exception. Small differences in manufacturing techniques and
material selection can increase the life of valves exposed to silica
and, often, corrosive agents and high temperatures, to a significant
degree. Valves are available in side entry, top entry,
floating and trunnion configurations

Valves
for petrochemical applications: Copeland has a variety of valves
for petrochemical service. Some are a plug valve design
but most use the variety of design features offerred by our BV
Series Valves. These can come with special linings or coatings for
dray abrasive conditions, high temperature alloys, metal coatings
that approach the hardness of diamonds and any number of options.
Copeland's latest series are bi-directional, top entry valves that
offer tight shut-off, low torques and can be used by themselves as
block and bleed valves. This is the first series of severe service
valves that are truly field servicable and are offered only at
Copeland. .
