5. We have three key people that have each been in the business for more than
thirty years, which means we have seen lots of valves and issues. We want
to bring that experience to work for our customers. It’s our reputation that
is at stake, and we do the “little things” to meet our goal of making valves
work in the shop and in the field. There is no overhead burden to influence
decision making, which enables us to serve our customers faster.
OUR GOAL IS TO MAKE OUR CLIENTS HAPPY
WE ARE DIFFERENT
WHY SHOULD YOU CHOOSE ALFA OILTECH ?
We do the “little things”
 We lubricate studs prior to tightening, which means 4x less torque is re-
quired to achieve the correct torque rating.
 We change ALL fittings to “USA” standards.
 We check bearing and gear operator lubrication and alignments.
 We functionally check all valves.
We assemble and test ALL valves in Houston, Texas.
We do not “shop the market” looking for low price deals.
We buy from selected known suppliers.
We test every valve according to the original design specifi-
cation or customer requirement.
We provide MTR’s and document packages on all products.

Expanding Gate
The AlfaGate E Expanding Gate
Valve design is the premiere choice
when a Full Port, Through Conduit,
Mechanically Sealing Gate valve is
required for flowline or geothermal
applications. The valve provides a
mechanically set seat second to none.
The optional AlfaKote protection
protects not only the seat and gate
sealing surfaces, but also prevents
corrosion in the entire body cavity and
wetted surfaces of the bonnet. The
AlfaKote protection also affords
lubricity and reduces operating
torques.

ALFAGATE S
Slab Gate
The AlfaGate S Slab Gate Valve is a full
port, through conduit gate valve designed
for geothermal wellhead and flowline
applications allowing easy and smooth
operation. Optimal clearances combined
with the through-conduit and full opening
design reduces turbulence and pressure
drop.
The seats function with pressure acting on
differential area. A basic law of nature
makes these valves seal, but they are also
fitted with emergency seat sealant
injection ports in case the seat or gate is
damaged. The hydraulic load applied by
the line pressure reduces when differential
pressures are lowered reducing the
amount of wear. The wear is much lower
than that employed by mechanically
energized configurations.

Alfa Oiltech, LLC through its
knowledge of high temperature and
high pressure corrosive and erosive
flow conditions has worked with the
coating industry to introduce
AlfaKote protection for those
applications that used to have a
devastating effect on valve life.
The AlfaKote coating provides
complete protection for those areas
in valves that used to be vulnerable
to the harsh conditions presented
by heavy brine conditions and the
volcanic ash and sand particles in
geothermal fluids.

47. Page 47
A L FA K O T E P R O T E C T I O N
The AlfaKote protection will extend
life, reduce torque, and provide years
of trouble free operation.
ALFAKOTE
AlfaKote is a aluminized ceramic base coat
and a propriety Ryton-PPS top coat
formulated for corrosion resistance,
toughness, impact resistance, and lubricity.
The AlfaKote system is referred to as a
"flexible ceramic" coating capable of
bending and flexing without breaking
through the coated surface and destroying
the protective barrier.
Tests in accordance with ASTM B117 on
scribed and unscribed coupons coated with
AlfaKote showed no signs of corrosion
after 2.75 years. The scribed coupon
showed only small amounts of white
corrosion at the edges of the scribe, but no
undercreep or blistering of the coating was
noted.
The materials used to product AlfaKote are
not new, but the process as developed by
Custom Coating Applicators is.The "Liquid
Powder" is applied in the desired areas, and
the liquid carrier is flashed away leaving
only the PPS resin on the sprayed surfaces.
The PPS resin melts at the bake
temperature and flows into the substrate.
The resultant products offers insulating
properties and lubricity reducing valve
torques and extending the life cycle.
Alfa Oiltech, LLC continues to
offer the latest in valve sealing and
operating technology, all with the
goal of reducing maintenance,
reducing operational headaches,
and reducing life cycle costs.
