Steel actuators

The TRIAC SY Series Scotch Yoke Actuators provide an ideal solution for applications where steel actuators are required due to corrosion protection requirements that aluminum actuators don’t adequately handle. Available in Double Acting and Spring Return, these quarter-turn actuators cover a broad range of torques (from 800 to 12,000 torque). The SY Series offers easy rotation selection from fail-closed to fail-open, by simply turning the actuator over and re-mounting. ISO mounting pad and Namur slots allow for quick, precise adaptation of control accessories, including limit switches, positioners, and feedback devices. Convenient jackscrew manual overrides provide for operation in the event of loss of plant supply air.
