I-Tork Controls | Electric and Pneumatic Valve Actuators, Limit Switches, and Flow Control Automation Systems



I-TORK Controls Ltd. is a South Korean manufacturer specialized in industrial heavy-duty automation. Their ITQ Series Electric Actuators are highly regarded for turning quarter-turn valves like ball, plug, and butterfly valves.
Key Technical Specifications
  • Torque Range: From 20 Nm (for small setups like the economy ITQ-0020) up to a massive 9,000 Nm.
  • Power Supply Flexibility: Compatible with 110/220 VAC (Single Phase), 380/440 VAC (Three Phase), and 24 VDC.
  • Robust Enclosure: Hard anodized aluminum casting with external epoxy powder coating. Weatherproofed to IP67 standard, with optional IP68 submersion protection.
  • Explosion-Proof Options: Certified versions are available for hazardous Zone 1 and Zone 2 environments.
Primary Product Lines
  • ITQ Series (Quarter-Turn): The core product line for standard industrial valve and damper automation.
  • E-ITQ Series (Economy): Cost-effective, compact variations engineered for smaller ball or plug valves.
  • ITL Series (Linear): Tailored for sophisticated linear travel automation systems.
  • ITS Series (Position Monitoring): Switch boxes configured with internal sensors to feedback live valve positions.
Core Built-in Features
  • Double Worm Gearing: Minimizes backlash and prevents reverse-torque back-driving, ensuring the valve self-locks safely in position without drawing excess energy.
  • Overheating Protection: High-starting-torque induction motors are equipped with integrated thermal protectors.
  • Manual Override: Includes an auto/manual switchable lever and handwheel for emergency mechanics during power losses.
These systems are widely used globally across petrochemical plants, waterworks, HVAC, power generation, and shipbuilding.
