Frequently Asked Questions

Scotch Yoke Actuators are mechanical devices that convert linear motion into rotary motion, commonly used for quarter-turn valve control.

These actuators utilise a yoke mechanism to translate linear motion into rotary motion, providing the necessary force to operate valves.

Scotch Yoke Actuators are often employed in industrial settings for on/off or modulating control of valves in processes such as oil and gas, water treatment, and power generation.

The symmetric yoke design ensures peak torque at both ends of the stroke, providing a well-balanced and reliable performance.

The canted torque arm design delivers peak torque at only one end of the stroke, potentially reducing actuator size, weight, and cost for specific valve applications.

Yes, Scotch Yoke Actuators are available in both GP (pneumatic) and GH (hydraulic) variants to accommodate different system requirements.

Factors include torque requirements, operating conditions, valve size, and the duty cycle of the application.

Yes, these actuators can be designed to handle high-pressure environments, especially in hydraulic applications.

Some models can be designed to meet explosion-proof or hazardous area certifications for safe operation in such environments.

Maintenance requirements typically include lubrication, periodic inspections, and, if needed, replacement of wearing parts.

The size is determined based on the torque requirements of the valve, taking into account factors such as pressure and temperature.

In many cases, yes. However, it's crucial to ensure compatibility and proper sizing during the retrofitting process.
