Durable, Precise Positioning Across Industrial Operations

Built to perform in the most demanding industrial environments, HercuLine electric actuators offer dependable, durable and accurate positioning for dampers and quarter-turn valves. They can also simplify system integration, helping organizations monitor performance and respond quickly when conditions change.

Precision positioning with non-contact sensing

Our advanced non-contact position sensing technology helps eliminates mechanical wear points that can affect accuracy over time. Digital feedback mechanisms help maintain consistent, repeatable precision throughout each actuator's service life. 

  • 0.2% repeatability across full span
  • Instant start/stop motor response
  • Reduced dead time and overshoot
  • Non-burnout continuous duty motor

Easy integration with control and management systems

HercuLine actuators can connect smoothly to building management systems and industrial controls. HART and Modbus RTU communication protocols offer flexibility for both existing infrastructure and future system upgrades. Personnel can also adjust actuator parameters remotely without manual intervention. 

  • Plant-wide system integration
  • Programmable output relays
  • Remote parameter access

Versatile solutions for multiple applications

We designed our actuators for deployment across diverse applications and temperature ranges. The wide operating range and multiple torque options can help reduce inventory complexity while meeting varied control requirements across facilities. 

  • Dampers and butterfly valves
  • Operating range: -40°F to 185°
  • Torque: 50 to 400 in-lb (2000 Series)
  • Torque: 10 to 300 lb-ft (10260 Series)1

Frequently Asked Questions About Process Instruments

Process instruments can measure, record and control critical process variables to support safer and more efficient industrial operations.

Specific applications include:

  • Temperature measurement and control
  • Pressure monitoring
  • Conductivity sensing
  • pH and ORP measurement
  • Flow control
  • Dissolved oxygen detection

These instruments help operators maintain product quality, reduce downtime and make informed decisions based on accurate process data.

Process instruments can work as an integrated measurement and control ecosystem within your automation infrastructure.

  • Actuators can execute control commands from controllers
  • Analytical sensors help provide continuous feedback to control loops
  • Controllers can process sensor data and adjust actuator positions
  • Recorders help capture system performance for analysis

This closed-loop approach helps maintain stable operations, respond to process changes and optimize performance across interconnected systems.

A phased approach to instrumentation upgrades can help achieve quick wins while building toward comprehensive process optimization. Start by assessing current measurement gaps and control challenges:

  • Identify critical process variables needing better visibility
  • Evaluate existing infrastructure compatibility
  • Consider environmental conditions and hazardous area classifications
  • Plan for integration with DCS, SCADA or PLC systems

Finish by considering training needs for operations and maintenance teams so that your whole organization is on board.
