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 band in the yoke mechanism, providing the greatest torque output at the beginning and end of stroke.
  • Heat-treated stainless steel thrust pin 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 allows for either parallel or perpendicular mounting.
  • Stainless steel construction allows proximity switches to be direct-mounted in the actuator housing, eliminating the need to mount bracket 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 eliminates the need for coupling.
  • Spring return model design requires no special tools to safely and easily disarm the spring in the field, reducing down time and providing a ‘man safe’ spring.
