Actreg Scotch Yoke Actuators

The Actreg Scotch Yoke Actuators boast external travel stop screws that facilitate precise valve angular stroke adjustments. This allows operators to tailor the actuator's performance with precision, enabling angular stroke adjustments ranging between 80º to 100º. This adaptability ensures optimal functioning tailored to the specific requirements of the application. Scotch Yoke actuators feature a modular design, allowing for the attachment of pneumatic or hydraulic cylinders on one or both sides. Additionally, for emergency shutdown (ESD) purposes, a spring cylinder can be installed on either side. With ample stock of finished and semi-finished components, actuators can be swiftly assembled and delivered reliably.

Pressure and Torque

HYDRAULIC PRESSURE: Hydraulic pressure refers to the force exerted by hydraulic fluid within a system. With a hydraulic valve actuator, pressures can reach up to 100 bar (equivalent to approximately 1449 pounds per square inch or psi). This level of pressure is significant and allows hydraulic actuators to generate considerable force, making them suitable for heavy-duty applications where high force output is required, such as in large industrial machinery, construction equipment, and hydraulic systems in marine and aerospace industries.

PNEUMATIC PRESSURE: Pneumatic pressure, on the other hand, is the force exerted by compressed air within the system. Pneumatic valve actuators typically operate at pressures up to 10 bar (approximately 145 psi). While pneumatic systems generally operate at lower pressures compared to hydraulic systems, they offer advantages such as simplicity, cost-effectiveness, and suitability for applications where cleanliness or explosion-proof operation is essential. Pneumatic actuators find widespread use in industries such as manufacturing, automotive, food processing, and pharmaceuticals.

TORQUE OUTPUT: Torque output refers to the rotational force exerted by the actuator's output shaft. Pneumatic valve actuators can deliver substantial torque outputs, with capabilities of up to 250,000 Nm (Newton-meters), which is equivalent to approximately 184,229 pound-feet (lbf). This high torque output enables pneumatic actuators to operate large valves and industrial equipment efficiently. It's crucial for applications where precise control over the rotational movement of valves or other mechanisms is necessary, such as in oil and gas pipelines, power plants, and chemical processing facilities.
