The Standard
in Non-Standard Valve Production
Our Business
CORTEC is a design, manufacturing, sales and service organization specializing in flow control applications.
We offer a line of equipment for use in a wide range of operational services, and we excel in providing solutions
to our customers’ needs when higher pressures, corrosive substances, or abrasive fluids are present. CORTEC
designs equipment to meet or exceed the requirements of the American Petroleum Institute Specification 6A.
Additionally, CORTEC's quality program is registered to the ISO 9001 and API Q1 quality standards.
The CORTEC brand comprises two globally established divisions:
Production & Extreme Service Chokes
Flowline Accessories
Turnkey Valve Manifold Packages
Compact Manifold Valves
Turnkey Valve Manifold Packages
Production Chokes
What should I consider before selecting a choke?
■
Working pressure and temperature
■
Inlet and outlet connections: size, type, etc.
■
Nominal body size
■
Trim type: tapered needle, cage and sleeve, rotating disc, positive bean, etc.
■
Means of operation: manual hand wheel or remotely actuated
■
Service conditions: corrosive, abrasive, sour
■
Flow media and specifications: oil, gas, water, gravity, etc.
■
Flow rates: minimum and maximum
■
Design and quality requirements: API, ANSI, etc.
We understand the importance of proper orifice sizing and its impact on your production.
Let us help you make the right choice.
Orifice Sizing and Selection
Probably the most misunderstood aspect of buying a choke is proper orifice sizing and trim style selection. It is
critical to the proper performance, function, service life and operator satisfaction. It is imperative that the choke and
it's associated components are properly selected based on the intended application. A choke that is equipped with
the optimal trim size and style will assure maximum service life, flowing performance and minimize down time.
CORTEC employs flow control sizing software based on the Instrument Society of America rules, as well
as years of experience and field confirmation. During the inquiry and sales process, we encourage the customer
to provide flow data and allow us to perform flow calculations. These calculations will aid in selection of the
correct orifice size and style and will allow us to make informed product recommendations. CORTEC can assist
this process by providing a data input form for the customer to complete.
Choke Bolting Dimensions
CORTEC chokes are manufactured to standard inlet and outlet dimensions. Our manufacturing process allows us
the versatility to supply chokes to custom inlet and outlet dimensions with a wide variety of common and custom
connections. This allows you to replace your existing choke without costly piping changes in the field.
