Water valve regulating gear
pt_111
Specifications
- Product Category: Precision Linear & Valve Control Components
- Drive Architecture: Gear-Driven Lead Screw & Nut Linear Assembly
- Configuration: Mated pair consisting of a gear-integrated lead screw shaft and a linear actuating nut
- Standard Materials:
Screw Shaft: Hydrolysis-resistant POM (Acetal), Glass-filled Engineering Nylon (PA66-GF)
Mating Nut: Self-lubricating POM, Wear-resistant Nylon, PPS, or Brass-insert composite - Primary Functions: Converts motor rotational torque into fine axial linear travel via precision lead screw and nut engagement, accurately regulating valve opening and water flow
- Applications: Smart Water Meter Shut-off Valves, Thermostatic Faucet Mixing Valves, Smart Irrigation Actuators, HVAC Water Control Valve Gearboxes, Underfloor Heating Manifold Actuators
Manufacturing Processes & Capabilities
- One-Piece Gear-Screw Tooling & Concentricity Control: Integrally molds the drive gear and lead screw shaft in a single shot; micro-tolerance tooling ensures strict lead accuracy, smooth thread flanks, and tight concentricity between the gear pitch circle and screw axis to eliminate rotational runout.
- In-Mold Rotary Core Unthreading: Mating nuts are produced via automatic rotary core-unscrewing tooling, yielding seamless, burr-free internal threads that ensure consistent, low-friction thread engagement under fluid pressure loads.
Features & Advantages
- Micro-Linear Travel & Precise Flow Regulation: Translates fine motor increments into smooth linear displacement, enabling precise, proportional valve aperture adjustment for consistent flow rate and water temperature management.
- High Thrust Capacity & Hydrostatic Self-Locking: Engineered thread geometry withstands high dynamic and static fluid pressures, providing reliable mechanical self-locking to prevent water pressure back-drive and leakage.
- Hydrolysis Resistance, Scale Prevention & Self-Lubricating: Formulated from potable-water-safe polymers that resist hydrolysis, moisture swelling, and mineral scaling; self-lubricating characteristics maintain low operating torque and maintenance-free reliability over the product lifespan.
