Stainless steel spring return and double-acting pneumatic quarter-turn actuators Output torques to 240,000 lb. in.

Features & Benefits:

  • Innovative stainless steel construction as standard provides superior corrosion resistance both internally and externally.
  • Scotch yoke design using precision bearings eliminates dead bands in the yoke mechanism, providing the greatest torque output at the beginning and end of the stroke.
  • Heat-treated stainless steel thrust pins and rollers transfer piston force to
    17-4PH stainless steel yoke by rolling to reduce friction, for longer life and more efficient torque transmission.
  • Bi-directional travel stops provide accurate valve rotation adjustment.
  • PTFE piston bearings, piston rod bushings, and output shaft bushings provide longer life, reduce maintenance, and require no lubrication.
  • Universal design position indicator and pointer allow for either parallel or perpendicular mounting.
  • Stainless steel construction allows proximity switches to be directly mounted in the actuator housing, eliminating the need to mount brackets and cam assemblies on top of the actuator.
  • NAMUR drive slot allows mounting of accessories closer to the actuator, resulting in a more compact, precise assembly, and eliminating the need for coupling.
  • Spring return model design requires no special tools to safely and easily disarm the spring in the field, reducing downtime and providing a ‘man-safe’ spring.
