High Torque Scotch and Yoke Actuator
Engineered for large valves requiring maximum torque output in demanding conditions.
How a Scotch Yoke Actuator Works
A scotch yoke actuator converts linear piston motion into quarter-turn rotary output through a yoke and slot mechanism. When compressed air or hydraulic pressure acts on the piston, it moves linearly inside the cylinder. This movement is transferred through the yoke, converting it into 90-degree rotational motion to operate the valve.
This design naturally generates higher torque at the start and end of the stroke, exactly where quarter-turn valves like ball valves and butterfly valves require it most. The result is smooth, efficient, and reliable valve operation even under high load conditions.
Applications
Scotch yoke actuators are used to automate large butterfly, ball and plug valves in oil & gas, power generation, water treatment and process plants requiring high breakaway torque.

Frequently Asked Questions
Answers to common questions about heavy duty scotch and yoke actuator, materials, sizing and selection.
A scotch yoke actuator is a pneumatic or hydraulic device that converts linear piston motion into rotary output to operate quarter-turn valves like ball valves and butterfly valves. The scotch yoke mechanism provides high torque at the beginning and end of the 90-degree stroke.
A single acting scotch yoke actuator uses spring return to move the valve to a fail-safe position when air pressure is lost. A double acting scotch yoke actuator uses air pressure for both open and close movements and holds its last position on air failure.
They are commonly used in oil & gas pipelines, chemical plants, refineries, power stations, and water treatment facilities to automate ball valves, butterfly valves, and plug valves.
Our scotch yoke actuators are rated for operating pressures up to 10 bar.
Yes. Standard models operate from -20°C to +80°C. High temperature variants are available up to +200°C.
Ball valves, butterfly valves, plug valves, and damper systems with quarter-turn operation are all compatible.
Yes. We offer customized torque solutions to match specific valve sizes and process requirements across industries.
Our heavy duty scotch yoke actuators comply with ANSI and ISO standards.
Scotch yoke actuators deliver higher torque at the start and end of the stroke, making them more suitable for heavy duty and large valve applications. They also have fewer moving parts, resulting in lower maintenance and longer service life.
Yes. Our heavy duty scotch yoke actuators are available in explosion-proof configurations suitable for hazardous area classifications in oil & gas, chemical, and petrochemical plants.
Scotch yoke actuators are used to automate large quarter-turn valves (butterfly, ball, plug) requiring high torque, particularly at the valve's opening and closing extremes.
Scotch yoke actuators deliver higher torque for a given size and are preferred for large or high-pressure valves, while rack-and-pinion actuators are more compact and cost-effective for smaller valves.
Yes, Concorde Valves supplies single-acting spring-return scotch yoke actuators for fail-safe (auto-close or auto-open) operation.
