Limitorque L120 Series: World-Class Multi-Turn Valve Actuators<\/strong><\/h1>\n

The Limitorque L120 Series<\/b> by Nippon Gear is a versatile electric actuator line designed to operate multi-turn valves with absolute precision. Featuring a rugged construction and intelligent control integration, the L120 Series is a trusted solution for critical infrastructure systems worldwide.<\/p>\n

Outstanding Technical Features of the L120 Series<\/strong><\/h2>\n

1. Ultra-Durable Housing \u2013 Defying Harsh Environments<\/strong><\/h3>\n
    \n
  • \n

    Premium Materials:<\/b> Utilizes die-cast aluminum (for smaller models) and cast iron (for larger models), optimizing weight while ensuring maximum structural rigidity.<\/p>\n<\/li>\n

  • \n

    Diverse Protection Standards:<\/b> Rated at IP55<\/b> (outdoor) with options up to IP67 and NEMA 4\/6<\/b>.<\/p>\n<\/li>\n

  • \n

    Explosion-Proof:<\/b> Meets stringent certifications such as JIS Exdll BT4, FM Class 1, and CSA<\/b>, making it suitable for the oil, gas, and chemical industries.<\/p>\n<\/li>\n<\/ul>\n

    2. High-Performance Gearing (Lifespan > 100,000 Cycles)<\/strong><\/h3>\n

    The combination of an aluminum-bronze worm gear and a Chrome Molybdenum steel worm shaft, lubricated with extreme-pressure grease, ensures smooth operation, minimized friction, and a service life spanning decades.<\/p>\n

    3. Intelligent Control & Absolute Safety<\/strong><\/h3>\n
      \n
    • \n

      Torque Switch:<\/b> Equipped with high-capacity silver contacts to provide instantaneous protection against valve overload.<\/p>\n<\/li>\n

    • \n

      Limit Switch:<\/b> High-precision intermittent gear mechanism prevents position deviation even after long-term use.<\/p>\n<\/li>\n

    • \n

      Safe Manual Operation:<\/b> Features an intelligent declutch lever. When the motor is activated, the device automatically resets from manual to electric mode<\/b> to prioritize remote control.<\/p>\n<\/li>\n<\/ul>\n
