FAQ
Questions Buyers Ask
Why choose scotch yoke over rack and pinion?
Scotch yoke actuators deliver more torque at the end of travel, where valve seating and unseating demand the highest force. For large valves (DN200+) or high-pressure differentials, scotch yoke is usually the right choice.
What is your largest scotch yoke actuator?
Our AW-series covers output torque up to 200,000+ Nm, suitable for valves up to DN1200 depending on pressure class. Contact us with your valve details for sizing.
Do you offer ATEX-certified scotch yoke actuators?
Yes. We supply ATEX-certified versions for oil & gas and hazardous area applications. Certification documents are provided with each unit.
