Exlar Electromechanical Actuators for Oil & Gas

Exlar offers reliable roller screw driven electromechanical actuators configured to meet the harsh demands of outdoor environments all over the world in oil & gas process control applications.

Electromechanical actuators are an ideal replacement for fluid powered actuation for those OEM’s looking to improve overall equipment effectiveness (OEE) with advantages in these areas:

  • Reliable to eliminate failures and downtime
  • Power dense to eliminate space needed
  • Accurate and repeatable to quickly adjust flow with no overshoot
  • Hazardous rated 
  • Electric to eliminate the need for pumps, compressors, hoses
  • Closed loop to offer constant and accurate feedback of valve stem position
  • Easy to configure/install through our process control specific software

Exlar electromechanical linear actuators transmit torque from the motor to force at the rod end using precision ground roller screws, these screws can provide advantages over other electromechanical linear technologies in these areas:

  • High rigidity - increases accuracy
  • Life - up to 15x longer than ball screws, even longer when compared to other screw technologies
  • Able to withstand high shock and vibration
  • Able to be taken apart for regreasing in the field

Eliminate Methane Emissions with Exlar Electric Actuators

For oil & gas production companies, methane emissions via pneumatic venting has become a major cost issue from lost gas revenue, potential fines, EPA reporting requirements and strict area classifications. Remote sites often use natural gas-powered pneumatic controllers for process control. The controllers are designed to continuously bleed natural gas resulting in significant methane emissions to the atmosphere. New studies are showing emissions from these low bleed pneumatic actuators are higher than original EPA national emission projections, which could impact the original regulations. In addition, the use of any device that vents methane in an enclosed area forces the area to be classified as Class 1 Division1 explosion proof, adding to the cost of equipment.

A solution to these venting problems is the use of an electric actuator in place of pneumatics, completely eliminating the venting of methane. This regains the lost vented gas revenue, reduces the need for emission monitoring and could allow for re-classification for many enclosed separator batteries to Class 1 Division 2 status.
