Stainless Steel Quarter-turn
Spring Return and Double Acting Actuators
Output Torques to 238,000 lb. in. (26,894 Nm)
Designed for 'on-off' or modulating control of any quarter-turn ball, butterfly, rotary plug or damper style valve applications. To be used in chemical process, food & beverage, iron & steel, off-shore marine, pharmaceutical, power, oil & gas, pulp & paper, and textile industries.
- 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
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.
