- An internal relay that eliminates the need for external-signal polarity reversal in order to change the direction of travel.
- Selection from 8 sizes ranging from 150 to 3,000 pound-inches.
- Easy installation and operation, making it ideal for field, offshore rig and remote skid applications.
- Compliance with NEMA 4/4X/7&9 standards and CSA, indicating that the actuators have been tested to both Canadian and U.S. standards.
