Servo Driven High Precision Auger Valve with 10~500 rpm Speed Range and 98% Repetition Accuracy for Stable Flow

Servo Driven Dispensing KSV series Concentric Screw Valve for smart manufacturing

The KSV1000 series is a screw valve specially used for quantitative delivery and dispensing of medium containing particles and medium-to-high viscosity media. The valve body is equipped with screws of different specifications, which can cover application scenarios with different flow and glue requirements. The valve body has a quick-release design for quick cleaning and maintenance.

The KSV3000 series is an upgraded version of the KSV1000 series screw valve, with a higher liquid flow rate, specially designed for dispensing high-viscosity media containing particles and heat conduction. The stator and rotor are made of high-wear-resistant materials to extend the maintenance cycle of core components.

Core Advantages

1. Equipped with a closed-loop servo motor, precise positioning, dispensing repetition accuracy can reach 98%, and the minimum glue output is 0.1ul.
2. The guide installation design of the rubber cartridge can adapt to 10/30/50ml rubber cartridges, which can be quickly replaced and easy to operate.
3. Equipped with a special negative pressure controller, the lower limit of the applicable medium viscosity can be reduced to 2000cps.
4. The screw is made of tungsten steel and has strong wear resistance for particles and medium and high viscosity media.
5. By controlling the forward and reverse rotation of the screw, abnormal problems such as glue drawing can be solved.
6. The universal downflow channel interface can match different downflow channels according to process changes to achieve rapid process switching.

FAQ

Q1: Can the concentric screw valve dispense precise amounts of adhesive without contaminating the lens or sensor?
A1: Yes. The valve offers highly accurate, repeatable dispensing with clean cutoff, minimizing stringing or overflow that could contaminate optical elements. It's ideal for precision bonding in confined optical assemblies.

Q2: How does the valve perform in narrow bonding areas like lens barrels or sensor modules?
A2: Equipped with fine Luer needles, the concentric screw valve can dispense in ultra-narrow spaces with precise control, enabling consistent glue placement in tight tolerance optical structures.

Q3: Will the valve cause bubbles or inconsistent flow during delicate dispensing?
A3: No. The continuous rotary screw mechanism eliminates pulsing, providing smooth flow that helps prevent voids or bubbles—critical in optical bonding for light transmission and durability.

Q4: Can the valve be integrated into a vision-guided, automated assembly system?
A4: Yes. It’s designed for seamless integration with robotics, motion platforms, and vision systems, supporting real-time alignment and high-throughput production in optical device manufacturing.
