Product Name: Series S Actuator

Product Description

Stainless Steel Spring Return and Double Acting Pneumatic Quarter-turn Actuators Output Torques to 238,000 lb.in. Features and Benefits: - 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 Namur 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 General Application: - For remote control of any quarter-turn application: ball, butterfly, rotary plug or damper style valves, etc. To be used in chemical process, food and beverage, iron and steel, off-shore marine, pharmaceutical, power, oil and gas, pulp and paper, and textile industries. Technical Data: - Supply Pressure : 40 to 160 psig (see torque charts) Supply medium : Air or any gas compatible with materials of construction Temperature rating: - Standard range : -20°F to 210°F Optional range : -65°F to 300°F Angular rotation : 90 degrees ± 8 degrees
