  • Ductile iron housing, piston and end caps provide long life and durable, cost-effective operation.
  • High strength alloy steel or 17-4PH stainless output shaft transmits torque without fatigue.
  • Sintered bronze or PTFE composite output shaft bushings eliminate side loading of valve stem to maximize stem packing performance.
  • Strong, corrosion-resistant chrome-plated steel piston rod for enduring high cycle applications.
  • Sintered bronze piston rod bushings provide low-friction support and precise alignment to increase efficiency, reduce maintenance and extend actuator life.
  • Heat-treated stainless steel thrust pin and rollers transfer piston force to yoke to reduce friction for longer life and more efficient torque transmission.
  • PTFE guide bands ensure low-friction piston guidance, protecting cylinder walls from scoring and extending seal performance with a continuous cylinder wiping action.
  • Bi-directional travel stops provide accurate valve rotation adjustment.
  • NAMUR drive slot maintains a compact assembly for accessory-driven components with no couplings necessary.
  • Tectyl-coated springs need no special tools to be disarmed safely and easily, reducing down time.
  • Easily removable housing cover provides easy access for yoke mechanism inspection.
