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.

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.
P Overall length of the positive model of the choke.

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
