Fisher 1061 Pneumatic Piston Rotary Actuator

The Fisher 1061 Pneumatic Piston Rotary Actuator is a compact, high-torque actuator designed to provide precise and efficient rotary motion for controlling quarter-turn valves such as ball, butterfly, and plug valves. Developed by Emerson, the 1061 actuator delivers reliable performance and long service life in demanding process control environments including oil and gas, petrochemical, and power generation industries. Utilizing a piston-driven mechanism, the Fisher 1061 converts pneumatic pressure into smooth rotary motion, providing high torque output with excellent control characteristics. Its double-acting design ensures consistent performance in both directions of travel, while an optional spring-return configuration offers a fail-safe mode for critical applications requiring automatic shutdown during air supply loss. The 1061 actuator features rugged, corrosion-resistant construction with high-strength steel and anodized aluminum components, ensuring durability even under extreme environmental conditions. It is designed for fast response, precise positioning, and minimal hysteresis, making it ideal for modulating and on/off valve applications. With ISO 5211-compatible mounting, multiple rotation ranges, and easy integration with Fisher positioners and controllers, the 1061 provides a flexible, efficient solution for both manual and automated control systems.

Feature of Fisher 1061 Pneumatic Piston Rotary Actuator

• Actuator is available in push-down-to-open or push-down-to-close construction and may be mounted in any of four actuator/valve body mounting positions.
• Single-point linkage with splined and clamped lever minimizes lost motion and improves control accuracy.
• Compared to similar actuators, overall size is reduced by as much as 30 percent.
• Rugged construction provides stability, corrosion resistance, and protection from deformation should the actuator be over-pressured.
• Actuator/valve body linkage is completely enclosed, yet the valve packing adjustment remains accessible without removing any parts.
• Highly visible travel indicator allows easy determination of valve position.
