Description
Single Acting Scotch Yoke Hydraulic Actuators, . These valve actuators are engineered to deliver exceptional torque and reliability, making them an essential component in industries where precision and performance are paramount.
Valve actuators provide a torque output of up to 250,000Nm (184,000 foot-pounds). Whether you’re operating in a chemical plant, mine, offshore drilling platform, or ship, our actuators are tailored to meet the most demanding conditions.
ISO5211 Standards: Scotch Yoke Hydraulic Actuator adhere to the stringent ISO5211 standards, ensuring superior connection dimensions and torque range.
Shift Fork Design: By significantly reducing lateral loads, our shift fork design enhances performance and longevity.
Modular Structure: Enjoy the benefits of easy maintenance and cost-effectiveness with our modular structure design, offering great interchangeability of parts.
Durability You Can Trust
Our actuators are built to last, delivering consistent and stable performance across various applications. The cylinder module features a built-in guide rod, solving the issue of local wear on the piston seal caused by lateral forces. This ensures a long-lasting and stable output, even in the harshest environments.
Customised for Your Needs
From choosing the right materials for different operating temperatures to selecting manual operation mechanisms such as handwheel, gear transmission, or hydraulic, our actuators are designed with your specific needs in mind. With symmetrical or tilted shift forks available, and an optimised transmission module and torque ratio, adaptability to valve torque has never been better.
Precision Control
Equipped with oil-free lubricated bearings made from aluminum bronze composite graphite, our shift fork transmission mechanism guarantees stable and durable performance. Additionally, a portion of the connecting shaft holes uses a square shaft to improve accuracy, making it especially suitable for regulating control valve applications.
Fail-Safe Options
Our single-acting Hydraulic Actuator offer fail-open or fail-close functionalities, ensuring that your operations remain safe and controlled even in emergency situations.

Single Acting Scotch Yoke Hydraulic Actuator FAQ
What is a Single Acting Scotch Yoke Hydraulic Actuator?
Single Acting Scotch Yoke Hydraulic Actuator is a type of actuator that uses hydraulic pressure to move a piston, which in turn moves a yoke to convert linear motion into rotary motion. This design is particularly effective for applications requiring high torque output at the beginning and end of the stroke.
How does a Single Acting Scotch Yoke Hydraulic Actuator work?
In a single-acting configuration, the actuator uses hydraulic pressure to move the piston in one direction, while a mechanical spring returns the piston to its original position when the hydraulic pressure is released. This setup ensures fail-safe operation, as the actuator will return to a default position in the event of a hydraulic failure.
What are the benefits of using a Single Acting Scotch Yoke Hydraulic Actuator?
- High Torque Output: Provides high torque at both the start and end positions, making it ideal for valve operations.
- Fail-Safe Operation: The mechanical spring ensures the actuator returns to a safe position in the event of hydraulic failure.
- Durability: Robust construction suitable for harsh industrial environments.
- Precision Control: Offers precise control over valve positioning, which is crucial for maintaining operational efficiency.
In what applications are Single Acting Scotch Yoke Hydraulic Actuators commonly used?
These actuators are commonly used in industries such as oil and gas, petrochemical, power generation, and water treatment, where they are utilised for operating various types of valves including ball valves, butterfly valves, and plug valves.
