Manufacturing Processes & Capabilities

• Elongated Multi-Stage Planetary Tooling & Assembly: Integrates a 1:720 high-reduction planetary gear system within a compact Φ33.5 mm × 85.6 mm cylindrical housing; micron-level tooling precision and multi-carrier alignment ensure strict concentricity and low backlash.
• Rigid Self-Lubricating Engineering Plastic Molding: Housings and gears are molded from high-grade POM and nylon with optimized mold flow shrinkage control, ensuring high structural integrity and dimensional stability under continuous high-torque operations.

Features & Advantages

• High Reduction Ratio & Superior Starting Torque: The 1:720 gear reduction amplifies motor torque to reliably overcome high initial breakaway torque and fluid resistance during valve opening/closing cycles.
• Wear-Resistant, Chemical-Resistant & Maintenance-Free: Self-lubricating POM and nylon materials offer excellent resistance to friction, humidity, and chemicals, ensuring long-term maintenance-free operation in demanding actuation environments.
• Coaxial Compactness & Quiet Operation: Symmetrical multi-planet load distribution ensures smooth power transmission, while engineered plastic gearing dampens meshing vibration for quiet, reliable valve regulation.
