44 Ball Valves
A quantum advance
in ball valve durability, cycle life, leak tightness and automation.
Flowserve Worcester
Controls Series 44 three-piece ball valves, for many years the most
respected ball valve design in the industry, are now better than ever. A
major research, design, and testing program brings you a new valve, designed
to ANSI B16.34 specifications with advanced seal technology and body mount
bracket design. This means a very strong, tough valve that can handle
pressure and unforeseen piping strains with a stem seal that extends
operational cycle life and a standardized overall design that keeps parts
inventory to a minimum. |
|
 |
Series
45 Ball Valves
Compact, Large
Diameter, Three-piece Ball Valves. Substantially Reduced Installation and
Maintenance Costs.
For OEM equipment
and packaged piping systems, Worcester Controls Series 45 ball valves
provide the best performance for the least installed cost in the 21/2"–6"
size range. Flanges are an integral part of the valve design, providing
savings in flanges, nuts, bolts and labor. Three piece construction also
means that the valve functions as both valve and union. This is a valuable
feature in welded piping systems where line breaks are required. |

Series
59 Ball Valves
Full-Port Ball
Valves. Manual and automated valves for processes requiring maximum flow
area.
Full-port ball
valves are recommended for processes requiring minimum restriction through
piping, shutoff valves, and other equipment. For example, pump inlet valves
are often full-port valves. Full-port valves are also useful in systems
handling slurries, viscous fluids and fluids with residues, and where the
capacity to pig lines is desired. |

High-Per Mizer
A High-Durability
Ball Valve for Superheated Steam, High-Temperature and Abrasive Fluid
Applications.
Metal-seated versions feature a unique and patented seat sealing design,
which incorporates an alloy stainless steel seat impregnated with
self-lubricating fillers. The rigid metal seat construction is strong,
highly wear and corrosion resistant, and eliminates fracturing common to
graphite-based seats.
Resilient-seated
versions feature High-Per Fill® seat. Proprietary to Flowserve Worcester
Controls, High-Per Fill is a blend of polyetheretherketone, glass and
graphite fillers. This blend strengthens, provides thermal resistance even
at high pressures, prolongs cycle life and reduces operating torque.
High-Per Fill is chemically inert, has a broad corrosion compatibility and
is a non-halogen (no TFE) material. |

Series D44/D4 Ball Valves
Diverter Ball
Valve - Separate Seats and Body Seals, One Flow Direction. The
diverter valve is designed to accept media through a bottom inlet port and
direct it out either of two outlet ports. It is commonly used for
alternately diverting flow from a single source to two different lines, for
example dumping operations in which one outlet permits media to flow from a
common source to the process while the other outlet alternately dumps or
recirculates excess media.
3-Way Ball Valve
- One Piece Seat and Body Seal, Bi-Directional Flow. The 3-way
ball valve provides greater flexibility in operation. Constructed with a one
piece seat and body seal, the 3-way valve permits flow in both directions.
It can function as a selector valve, alternately accepting media from either
of two inlet sources and directing through a single outlet. Or, it may be
used as a true 3-way valve, accepting media from two inlet sources for
alternate discharge through either of two outlet ports. For example, in a
pressurized line or system, the inlet port pressurizes or fills the system.
The valve is then operated through its travel to allow the pressurized
contents to be discharged through the second outlet port with the original
outlet port now functioning as the inlet. |
|
 |
Series D51 Ball Valves
A Simple,
Dependable Way to Divert Flow to Two Pipe Lines with Tight Shutoff to Either
Line. Worcester’s Series D51 is a standardized line of flanged
diverter ball valves in sizes 2", 3", 4", 6", and 8" with ANSI Class 150
flanges. D51 diverter valves are designed to accept media through a bottom
inlet port and direct it out either of two outlet ports. They are commonly
used for alternately diverting flow from a single source to two different
lines; for example, dumping operations in which one outlet permits media to
flow from a common source to the process while the other outlet alternately
dumps or recirculates excess media. |
