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.
