 Product Brochure

• 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.
• Precision roller bearings, made from hardened stainless steel, produce a longer-lasting, high performance actuator.
• Bi-directional travel stops provide accurate valve rotation adjustment.
• Teflon^® 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.
• Actuator 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.
