Compact Design, High-Precision Torque-Grat 20Nm IoT Micro Electric Actuator Enabling Next-Gen Industrial Automation

Key Features: In industrial automation, actuator performance is critical to system stability and efficiency. GRAT's 20Nm IoT Micro Electric Actuator (WA-20PCU) combines compact design, high torque, and smart connectivity, optimized for quarter-turn valves (butterfly, ball valves, dampers). Ideal for industries like chemical, power, and wastewater treatment, it excels in applications such as burner gas flow control and mineral processing.

1.Four Key Advantages for Grat 20Nm IoT Micro Electric Actuator

①Compact & Space-Saving Design
With 1/3 smaller volume than conventional actuators of the same torque, its lightweight body and compact design save 30% installation space. Ideal for confined spaces like narrow pipelines or integrated equipment.

②High Torque & Energy Efficiency
• 20Nm Rated Torque: Effortlessly operates ball valves up to DN25, even with high-viscosity media.
• Low Power Consumption: 10W design reduces energy use by 50%. Features a brushless motor with overload protection for extended lifespan and reliability.

③Smart & Precise Control
• 30-100% PWM Speed Regulation: Smooth operation with 0.5% position accuracy, ideal for burner adjustments.
• Modbus Integration: Supports Modbus RTU/TCP for seamless PLC connectivity. Real-time status monitoring via OLED display with fault alerts.

④User-Friendly & Fail-Safe
Manual/auto dual mode with hex wrench for quick emergency override during power failure, minimizing downtime.

2.Typical Application

Scenario 1:Burner Gas Flow Control
In gas systems, the EA-20 adjusts valve openings via Modbus the accuracy reached 0.5%.PWM speed regulation ensures smooth flow control, stabilizing flame while reducing energy costs.

Scenario 2: Automated Valve Control for Desliming Bucket in Mineral Processing
In mining production lines, the EA-20's compact design fits confined spaces atop desliming buckets. It provides real-time valve position feedback via 4-20mA signal, while its torque-limiting mechanism prevents jamming and offers overload protection. The manual override function ensures quick maintenance and minimizes downtime, guaranteeing continuous operation.
