Bettis Stainless Steel M Series

Brand: Bettis - by Emerson Electric Co.

The Bettis Stainless Steel M Series is designed for reliable performance in the harshest environments.

The all stainless steel construction resists corrosion in a variety of demanding applications from chemical processing to power, water wastewater, oil and gas, and mining. 

This high-performance actuator is built tough with stainless steel cylinders and PFTE piston bearings to provide longer life and reduce downtime.

The man-safe spring design requires no special tools to disarm springs safely and easily. This tough actuator is designed and built in the USA for reliable performance in the severest environments.
  • Innovative stainless steel construction provides superior internal and external corrosion resistance
  • 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
  • High strength 17-4 PH stainless output shaft transmits torque and gives long service 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
  • 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
  • NAMUR drive slot maintains a compact assembly for accessory-driven components with no couplings necessary
  • Available in symmetrical and canted yoke design to suit application
  • Spring return model design requires no special tools to disarm springs safely and easily, reducing down time
