Features

  • Available with fail-open or fail-close construction and can be mounted in any of four actuator/valve mounting positions. These actuators can be mounted on a broad range of Fisher valves or used with other equipment.
  • Single joint linkage with splined and clamped lever minimizes lost motion and improves control accuracy.
  • Rugged construction provides stability, corrosion resistance, and protection from deformation should over-pressurization occur.
  • Includes an externally accessible spring adjuster to relieve spring compression. Actuator/valve linkage is completely enclosed, yet the valve packing adjustment remains accessible without removing any parts.
