The R series electric actuator is an intelligent part-turn industrial execution unit integrating precision mechanical transmission with advanced electronic control technology. Designed specifically to drive ball valves, butterfly valves, dampers, and various rotary mechanisms, it facilitates automated shut-off or continuous proportional regulation of fluid media. The core power system supports multiple voltage inputs (AC 110V/220V/380V) and accepts standard 4-20mA DC, 1-5V DC analog signals or switch signals. Renowned for its compact layout, powerful torque output, and superior protection, the R series is widely applied in petroleum, chemical, power, metallurgy, water treatment, and BAS systems to ensure process precision and safety.

1.Wide torque output range:Provides stable torque output from 50N.m to 2000N.m. The precision-engineered reduction mechanism ensures smooth and efficient transmission, meeting the demands of large-diameter valves and high-pressure conditions.
2.High-grade protection system:Housing protection reaches IP67 or IP68, offering excellent dust and water resistance. Specialized sealing ensures reliable long-term performance in humid, rainy, and harsh outdoor industrial environments.
3.Multi-voltage and signal compatibility:Supports global voltage standards and features a highly integrated control module. It offers strong anti-interference performance, high-resolution positioning, and real-time status feedback.
4.Reliable mechanical self-locking:Utilizes a precision worm gear structure for inherent self-locking. During power loss or sudden pressure surges, it firmly holds the valve position to prevent accidents caused by uncontrolled flow.
5.Versatile mounting angles:The balanced structural design allows the actuator to be installed at any angle—horizontal, vertical, or tilted. This flexibility facilitates engineering layouts in dense piping or narrow spaces.
6.Seamless manual-auto transition:Equipped with an independent manual handwheel for a smooth override experience. During commissioning, maintenance, or power loss, operators can quickly intervene manually to maintain continuity.
7.Comprehensive intelligent protection:Integrated with electronic limit switches, overload torque sensing, and motor thermal protection. Supports fail-in-place logic and self-diagnostic alarms to keep the equipment in a safe state.
8.Low maintenance and long life:Core bearings and transmission pairs feature long-term lubrication for minimal mechanical wear. The modular circuit board design allows for rapid onsite replacement and upgrades, lowering lifecycle costs.
