Model 88-109: Precision Multi-Turn Rotary Actuator for High-Duty Cycle Applications

The Harold Beck Model 88-109 is a state-of-the-art multi-turn actuator engineered for demanding rising and non-rising stem gate applications. Combining the legendary reliability of Beck’s no-burnout motor technology with a unique multi-turn design, this actuator is the ideal solution for large butterfly valves and critical process control loops. Designed for 100% continuous duty, the 88-109 ensures your operations remain stable and precise without the periodic maintenance or overheating risks associated with traditional multi-turn drives.

Built with a rugged NEMA 4X, IP68 rated enclosure, the Model 88-109 is capable of withstanding submersion and extreme industrial environments. It features advanced digital control capabilities, including Wi-Fi and HART configuration interfaces, allowing for seamless integration into modern automation systems. Whether managing water treatment facilities or power generation plants, the 88-109 delivers high-speed response and repeatable accuracy, backed by a maintenance-free gear train and a design that is proudly made in the USA.
