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. CORTECdesigns 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 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 iscritical to the proper performance, function, service life and operator satisfaction. It is imperative that the choke andit's associated components are properly selected based on the intended application. A choke that is equipped withthe 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 assistthis 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 usthe versatility to supply chokes to custom inlet and outlet dimensions with a wide variety of common and customconnections. This allows you to replace your existing choke without costly piping changes in the field.

Type Dimension Description

I Inlet dimensions are from the centerline of the outlet to the face of the inlet flange.

O Outlet dimensions are from the centerline of the inlet to the face of the outlet flange.

P Overall length of the positive model of the choke.

A Overall length of the adjustable model of the choke in the fully closed position.

ACTUATEDYOKE

Choke Actuation

CORTEC supplies various proprietary actuators and associated instrumentation to complement its comprehensiverange of chokes. Advanced actuators and instruments are available for a complete flow control solution. Some actuator options available include:

Electric ActuationBettis® TorqPlus™ Model "EM-510" multi turn actuator.

The low friction high torque CORTEC open yoke adaptor converts rotary motion of the actuator to a high thrust linear motion.

Features and Benefits

• Manual override• Weatherproof aluminum housing to

A356-T6 specifications• Class 1, Division 1 Group C&D electronics• Local position indicator• Precise repeatability• Low power consumption• Analog and digital interface• Three limit switches• Dual conduit entries• Upon loss of control signal this unit can be

configured to fail in place, fail open or fail closed• Upon loss of power source the unit will fail in the last position• Powered by optional 12 or 24 VDC or 115 or 230 VAC• The actuator and open yoke unit weighs 55 lbs (24.95 kg)• OHC-400 positions can be field-converted to utilize digital

communication protocols such as MODBUS

High thrust and remote operating ability to meet the mostdemanding applications.

Hydraulic Piston Actuation

CORTEC's Hydraulic Piston actuators are double acting with a linear motion. Hydraulic pistons are the preferred actuator of many oilfield applications, and are favored for theirhigh thrust and rugged reliability.

Typically used in high pressure manifold applications and rugged service related environments.

Pneumatic Diaphragm Actuators

Pneumatic diaphragm actuators are supplied with fail openor fail close operation. Available with position and control instrumentation to meet your requirements.

Features and Benefits

• Available with position and control instrumentation to meet your requirements.

• This model is typically supplied with: • Pneumatic or electro-pneumatic

positioners• Filter regulator• Stainless steel tubing and fittings

Supplied with fail open or fail closeoperation.

Pneumatic Linear Piston Actuators

Features and Benefits

• Available in double acting, fail open or fail close.• Can be supplied with a variety of instrumentation

and controls to suit customer requirements.• Actuator and positioner can be operated using

instrument gas• Electrical classifications include

Explosion proof or Intrinsically safe and can be in compliance with the ATEX directive.

• Manual override available

For applications where pneumatic is the desired power source, linear piston actuators provide reliable high thrust in a simple and reliable design.
