Megawatt Machine Services specializes in providing complete project support for severe-service
valve repair, replacement parts and field service. And here at MMS, we understand the importance of
companies requiring traceability and the guarantee of dependability on all their valve repairs and new valve
parts purchases. That’s why we have implemented the strictest of quality-control programs by becoming
ISO-9001:2008 and NUC 10CFR50 Appendix-B certified. By using MMS, not only do our
customers receive valve services for a fraction of the OEM price, faster delivery times, and
longer usage-life of their valves, but also the comfort of knowing all their parts and services
performed are provided through an elite Quality Management System(QMS). Make the right choice.

called “Microscopic-Welding”. In
utilizing this technique, plants are

Hard-SurfaceOverlay
Here at Megawatt Machine Service, our specialty is in the
manufacturing and rebuilding of control valve components.
For the last 40 years we’ve set the industry standard in
producing congruent O.E.M. valve trim parts such as plugs,
stems, cages, seats, bonnets and guide bushings for
virtually every control valve manufacturer in all shapes and
sizes. We can reverse-engineer any valve part, new or used,
with our hi-tech CMM equipment. MMS stocks a wide range
of mill-certified metals and alloys such as multiple varieties of
stainless steel, Inconel®, Hastelloy® and tungsten-carbide.
Our in shop capabilities range from state-of-the-art CNC
machining to precision grinding to hard surfacing and
coatings such as Stellite® overlay, Ion-Nitride, heat-treating
and HVOF. MMS can apply hard-surfacing on all critical
areas such as seated and wear locations in order to extend the
user-life of your valves. This hard surface provides protection
against cavitations, flashing / erosion, vibration / noise,
turbulence, corrosion and abrasion that can so often occur.
MMS also prides itself on providing emergency services and
exceptionally fast delivery on all new parts and repairs,
especially during forced outages. If you have a valve
question or need support, please call one of our sales reps
for immediate assistance.
Provided Below is a partial listing of

PTA Weld-Overlay on Turbine-Bypass Plug PTA Weld Repair on Stop-Check MOV
PlasmaTransferArc(PTA)viaSTELLITE®Coatings
Plasma Transferred Arc System (PTA) is a high energy, inert gas welding process. Argon is used for arc plasma
supply, powder transport and molten material shielding. It produces a very high quality deposit offering optimal
protection with minimal dilution or deformation of the base material. It is a process that deposits very precise
coatings of perfectly controlled alloys on mechanical parts that are subject to intense wear, significantly
extending their service life. PTA technology is particularly effective in protection against corrosion, thermal
shock and abrasion. A wide range of overlay alloys is available for practically any part. Some alloys are
very hard, others are softer with abrasion-resistant particles dispersed in a matrix. Certain alloys are made
to rebuild apart to a required dimension while others are designed to be a final overlay that protects the
work surface. Please contact an MMS sales rep for more info and a visit to our facility for a live demo.
Turbine Valve Parts&Repair
Megawatt Machine Services has been
remanufacturing and rebuilding steam turbine
valve parts for over 40 years. We use only the
highest quality of hard-surfacing materials
and ion-nitride equipment to ensure
our products leave our plant equal to or
exceeding the OEM’s specifications. Over
the years we’ve serviced turbine valve
components for power generating stations
all over the world that use a variety of
manufacturers such as: ABB-Alstom, GE,
Siemens-Westinghouse, Toshiba and
Elliot. With our state of the art machining and
precision grinding facility, there is not a
valve component that we can’t handle.
Megawatt’s impeccable services are
established upon the lowest pricing and
expedited delivery times to make sure
our customers don’t have to settle for the
OEM’s overpriced rates and belated
delivery times. Please call one of our
reps for further info.
MMS provides re-engineering and manufacturing for valves and components from all turbine manufacturers. We can upgrade design flaws and incorporate upgraded materials. The result is longerservice life and less maintenance expense. With many years of in-house engineering experience and a vast parts database, MMS is your best source for valve components. We offer inspection, repair, restoration and upgrades for many types of valves: main-stop, reheat, intercept, control and governor. We manufacture valve stems, discs, bushings, caps and hardware for steam turbines of virtually every OEM.

PrecisionReverse-Engineering
Reverse engineering is a dedicated and precise process that Megawatt Machine Services uses to create a 3-Dimensional surface drawing or solid model of an existingpart. These drawings can then be used to modify the existing part or to machine a new one exactly to OEM specs. The data collection process is accomplished by utilizing any or all of the following methods:
• CMM Inspection • Optical Digitizing •Physical Measurement •NDE Testing •Laser Inspection
The collected data is then processedusing high-tech software programs toprepare it for integrating into a CAD model.The finished CAD model is then detailedor modified to the customer’s specificationsand design enhancements. And finally it isprepared for converting to Master-CAM andprocessed for manufacturing. Please feel free to contact one of our sales representativeswith any questions and to find out how we can further assist you in this area.
