Large‑Flow Concentric Screw Valve

  • Model: TD-SPG01
  • Drive: Servo motor
  • Viscosity: 6,000–1,300,000 cps
  • Repeatability: ±1.0%
  • Inlet: Luer connector
  • Wetted parts: SUS304

The TD-SPG01 Large-Flow Concentric Screw Valve adopts a coaxial screw-sleeve structure with servo-driven volumetric delivery. The large-pitch screw is engineered for smooth, continuous dispensing of medium-to-large volumes. Co-axial operation minimizes fluid pulsation and delivers powerful thrust, while the dispensing flow stays strictly proportional to motor speed — virtually unaffected by tank pressure or glue-level fluctuation. A reverse-rotation suck-back function effectively prevents dripping and stringing.

 

Key Features

  • Conical nozzle for consistent, repeatable bead shape
  • Adjustable dispensing volume
  • Built-in heating block & RS232 interface
  • Adjustable screw speed for flexible process control
  • Multiple alloy material options for fluid-contact parts
  • Motor option: AC servo motor
  • TC-pattern screw structure — optimized cost-performance balance
  • Signal-controlled operation, compact mounting footprin

Compatible Materials

Designed for thermal conductive gel, high-filler thermal grease, sealant, silicone, solder paste, high-viscosity structural adhesive, and other medium-to-ultra-high-viscosity paste fluids with solid fillers.
