High Precision Volumetric Auger Valve with 1 μL Minimum Dispensing and 0.01 to 1.2 mL/min Flow Rate for 10 ℃~40 ℃ Operating Temperature

High-precision Volumetric Auger Valve KSP0150 applicable for CCM, FPC, PAD

The micro-volume dispensing screw valve KSP0150 is a high-precision, volumetric dispensing solution designed for consistent and accurate delivery of single-component fluids in micro-quantities. Utilizing an eccentric rotor-stator mechanism and brushless servo motor drive, it ensures stable flow control across a wide viscosity range—from low to highly viscous materials. With a dispensing volume as low as 1 μL and volumetric flow rates from 0.01 to 1.2 mL/min, this valve is ideal for applications in electronics, semiconductors, medical devices, and precision assembly. The micro screw valve provides excellent repeatability, minimal shear stress, and reliable performance in automated production environments. It is suitable for dispensing adhesives, UV glue, thermosetting adhesive, one-component epoxy resin, and other challenging fluids. Designed for durability and easy integration, it offers exceptional control for micro-dispensing needs.

Core Advantages

• Ensure mixing ratio accuracy (2-K type, KDP0300)
  The controller tracks the glue level of the two-component glue supply system in real time. When a level difference occurs in the two-component glue barrel, the system feedback control algorithm makes a slight adjustment when the screw valve is discharging glue, realizing automatic compensation of the level difference and ensuring the accuracy of the glue mixing ratio.
• Ensure process stability (2-K type, KDP0300)
  The electronic refrigeration device with a temperature of -10°C directly covers and refrigerates the mixing tube filled with glue, delays the curing time of the glue when mixing, and ensures the process.
• Process capability guarantee (2-K type, KDP0300)
  Real-time monitoring of the glue flow channel pressure during the screw valve dispensing process, identifying glue curing and blockage, and improving the process control capability.

Main appliaction

Pad assembly, car camera AA, VC heat spreader, mobile phone camera module conductive glue, PAD magnet bonding, mobile phone motherboard thermal grease.

FAQ

1. What is the minimum dispensing volume achievable with a micro screw valve?
Micro-volume screw valves can dispense as little as 1 microliter (μL) with high precision, making them ideal for ultra-small dot or line applications.

2. Can the screw valve handle high-viscosity or filled materials?
Yes. Thanks to its volumetric eccentric screw design, it supports a wide viscosity range, including high-viscosity adhesives, pastes, and filled fluids without clogging or dripping.

3. How does a micro screw valve ensure consistent dispensing accuracy?
The valve uses a servo-driven rotor-stator mechanism that delivers stable volumetric flow, ensuring excellent repeatability and minimal fluid shear, even during long dispensing cycles.
