Choke Actuation

Electric Actuation

Bettis® 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.

Superior thrust to meet the most demanding applications.

Features and Benefits

• Manual override
• Weatherproof aluminum housing
• Explosion proof electronics
• Local position indicator
• Precise repeatability
• Low power consumption
• 4-20 ma control signal and position feedback
• 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)

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.

Used in high pressure manifold applications and rugged environments.

Pneumatic Diaphragm Actuators

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 close operation.

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.

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