Scotch & Yoke Pneumatic Actuator – DA, SA Series

The Scotch & Yoke Pneumatic Actuator is a heavy-duty, high-torque valve automation solution designed for severe and safety-critical industrial applications. Using the proven Scotch & Yoke mechanism, the actuator converts linear piston motion into powerful rotary output, delivering maximum torque at breakaway and seating positions—where valves demand the highest force.

Available in Single Acting (Spring Return – Fail-Safe Open or Close) and Double Acting (Air-to-Open / Air-to-Close – Fail-Stayput) configurations, these actuators are ideal for operating large ball valves, butterfly valves, plug valves, dampers, and emergency shutdown systems. Their rugged construction, optimized torque curve, and air-driven operation ensure reliable performance under high pressure, high friction, and continuous duty conditions.

With ISO/NAMUR compliant mounting and compatibility with automation accessories, Scotch & Yoke actuators provide dependable, long-life operation across oil & gas, petrochemical, power, water, and heavy industrial applications.
