We have an extensive experience in the design and manufacturing all type of Scotch Yoke Actuators for on/off or Emergency shut down & Blowdown services.
The Scotch Yoke actuator is designed for providing peak of torques at the break and end points of the stroke, ensuring the maximum reliability. For this reason, the actuator mechanism is available in both symmetric and canted design to meet specific demands. 
The mechanism is fully contained in a housing designed and tested against full differential pressure. To minimize cost and weight actuators have a modular construction. The hydraulic/pneumatic cylinder and the spring cartridge can be connected to the left or to the right side of the housing to fit with the requested fail action.
For heavy duty high performance, we have a dedicated line of single acting compact actuator, in which the cylinder assembly contains the spring as well.
