Precision Engineering & Internals

  • Motor Design: Engineered with a 1.3x - 1.5x torque reserve, allowing the actuator to handle frequent starts and temporary overloads without failure.

  • Transmission System: * Worm Gear: Forged aluminum bronze alloy for high strength.

    • Bearings:EMQ (ZV2) P6-grade precision bearings for low noise and vibration.

  • Easy Commissioning: Proprietary top-mounted "adjusting shaft" allows for simple and precise stroke limit settings.

  • Lubrication: Lifetime pre-filled with imported Mobil synthetic grease.

Quality Control & Manufacturing Excellence

Produced by engineers with 10+ years of experience using UG 3D simulation, our manufacturing process includes:

  1. CNC Precision: Processed by imported 4-axis machining centers and verified by CMM (Coordinate Measuring Machine).

  2. Strict 4-Step Pre-shipment Testing:

    • Torque Margin Test: Verification of 1.3x rated load capacity.

    • Insulation Test: 1500V high-voltage breakdown resistance.

    • Load Endurance: 48-hour continuous full-load cycle testing for batch samples.

    • Extreme Waterproof Test: Submerged IP68 test at 0.2Mpa for 10 minutes to ensure absolute sealing integrity.

Primary Application Fields

  • Heavy Industry: Steel mills, metallurgy, and mining.

  • Energy Sector: Hydroelectric and Thermal power plant valve control.

  • Infrastructure: Large-scale water treatment and electric irrigation.

  • Process Industries: Petrochemical, paper making, and pharmaceuticals.
