Product Description
Product Overview
The Fisher™ 1052 Pneumatic Rotary Actuator is a versatile and robust spring-return rotary actuator designed for reliable operation in both on/off and throttling control applications. Engineered to provide precise control for rotary valves such as ball valves, butterfly valves, and eccentric plug valves, this actuator delivers exceptional performance across various industrial processes.
A key design advantage of the 1052 actuator is its adjustable spring mechanism. This innovative feature provides outstanding application flexibility, allowing the actuator to be used with or without a positioner for throttling control, adapting seamlessly to your specific process requirements.
Key Features & Benefits
🎯 Flexible Application & Control: Suitable for both on/off and throttling applications. The adjustable spring mechanism enables operation with or without a positioner, providing exceptional adaptability to varying process conditions.
⚙️ High Precision & Fast Response: Features splined and clamped linkage connections that minimize backlash, significantly improving control accuracy. The optimized design ensures rapid response times for enhanced process control.
🛡️ Long Service Life & Safety: Robust construction delivers excellent stability and corrosion resistance. The design protects against deformation under overpressure conditions. The fully enclosed actuator-valve connection maintains safety while allowing valve packing adjustment without component removal.
🔧 Flexible Installation & Vibration-Resistant Design: Available in fail-open or fail-close configurations with four possible mounting orientations. Compatible with various Fisher® valves. The 1052PSV version incorporates a tilted diaphragm stem, adjustable sleeve nut, upper diaphragm assembly, and SS129 dual springs within a welded housing, featuring a seismically qualified design.
