Advanced Smart Lq3 Electric Actuator with 90-Degree Valve

Product Description

 

LQ quarter-turn electric actuator for valves with 90 degree movement 

 

Key Features:

• High Torque Output: Delivers torque output up to 2000 Nm, suitable for controlling large-diameter valves.
• Intelligent Control System: Supports various industrial protocols such as Modbus and Profibus, making it easy to integrate with PLC and DCS systems.
• Accurate Position Feedback: Utilizes advanced angle sensing technology to ensure valve opening precision down to 0.1%.
• Automatic Fault Detection: Built-in intelligent diagnostics system that detects the actuator's working condition in real-time and provides alerts.
• Manual Operation Capability: Equipped with an emergency manual operation mechanism for manual intervention in case of power failure or malfunction.
• Fully Sealed Protection: IP67 protection rating, making it waterproof and dustproof for harsh working environments.
• Low Power Consumption: Designed for energy efficiency, reducing long-term operating costs.

 

Instructions for Use:

1. Installation Preparation: Ensure the valve and actuator flange installation positions are aligned, tighten all bolts, and ensure firm installation.
2. Power Connection: Connect the electric valve actuator to a 220V power supply. Refer to the product label for specific voltage requirements.
3. System Setup: Set parameters such as stroke limits, torque settings, and switching logic via the control panel or upper-level computer.
4. Testing & Operation: Perform manual mode testing before running the actuator to ensure accurate valve positioning at full open and full close. Switch to automatic mode after successful testing.
5. Regular Maintenance: Check the device quarterly to ensure proper sealing, wiring, and transmission mechanisms. Lubricate and replace parts as necessary.

 

Customer Reviews:
