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 androllers 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.
