Skotch Yoke Pneumatic Actuator

“aline” Make Scotch Yoke Pneumatic Actuator is a heavy-duty quarter-turn actuator engineered to deliver high output torque, exceptional durability, and reliable performance for demanding industrial valve automation applications. Designed with an advanced Scotch Yoke Mechanism, it generates higher breakaway and end-position torque than conventional rack & pinion actuators, making it ideal for operating large Ball Valves, Butterfly Valves, Plug Valves, Dampers, and other high-torque quarter-turn valves.

Manufactured using a rugged S.G. Iron body, precision-machined alloy steel yoke, and premium sealing materials, the actuator offers outstanding strength, corrosion resistance, and long operational life. Available in Double Acting and Spring Return (Fail Safe) configurations, ALINE Scotch Yoke Pneumatic Actuators ensure smooth operation, reliable automation, and minimal maintenance even in the most demanding industrial environments.

Suitable for Oil & Gas, Petrochemical, Power Plants, Refineries, Chemical Industries, Steel Plants, Marine, Offshore Platforms, Water Treatment, and Process Automation, these actuators provide dependable performance for critical valve automation systems.
