FEATURES AND BENEFITS

• 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 17-4PH 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.
