    CORTECis 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'squality program is registered to the ISO 9001 and API Q1 quality standards.

    The CORTECbrand comprises two globally established divisions:

    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.

    CORTECemploys 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. CORTECcan assistthis process by providing a data input form for the customer to complete.

    Ch%!e B%")$g D#e$(%$(

    CORTECchokes 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.

    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.

    CORTECsupplies various proprietary actuators and associated instrumentation to complement its comprehensive

    range 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 CORTECopen yoke adaptorconverts 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 most

    demanding 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 their

    high 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 open

    or fail close operation. Available with position and controlinstrumentation 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
