Product Description

Product Description

Plunger Valve (Needle Dispensing Valve)

The plunger valve, also recognized as a needle dispensing valve, is meticulously engineered for the precise and consistent dispensing of low- to medium-viscosity fluids. Its operation hinges on a vertically moving plunger that opens and closes the fluid path, ensuring superb shot size control and delivering a sharp, clean cut-off to prevent drips.

With its rapid response time and exceptional dispensing accuracy, the plunger valve is highly sought after in sectors like SMT assembly, microelectronics, medical devices, and general adhesive dispensing. It excels in delivering UV adhesives, cyanoacrylates, solvents, oils, and other materials that cure rapidly or possess low viscosity.

Available in both pneumatic and solenoid-driven configurations, plunger valves are adaptable to manual and fully automated systems alike. They feature adjustable stroke and interchangeable needle/nozzle sizes, allowing seamless customization for a diverse range of process requirements.

Key Features:

- Quick open/close action ensures high-speed dispensing

- Clean shut-off guarantees anti-drip performance

- Versatile compatibility with a wide array of low-viscosity materials

- Streamlined design perfect for integration into robotic or benchtop systems

- Optional heating and vacuum assist for tackling challenging applications

Advantages:
1. Simple and swift maintenance, minimizing downtime and maximizing operational efficiency.
2. Exceptional longevity coupled with cost-effectiveness, offering outstanding value.
3. Dramatically reduced servicing costs, boosting overall profitability.
4. Optional enhancements such as valve monitoring, mixing tube heating, and dispenser heating for tailored performance.
5. Remarkable flexibility of the system, tailored to meet any specific requirements with ease.

To boost production capabilities, we've ingeniously developed 2 and 4 needle modules. These modules are ideal for simple dispensing and compact products, maintaining precision while enabling the simultaneous completion of multiple items, thus enhancing productivity and efficiency.

Specification

Volumetric piston dispensers are the epitome of versatility, adept at handling both extremely fluid and highly viscous media. They excel in applying filled and/or abrasive substances as well as 1K and 2K casting resins, indispensable for filling, sealing, and adhesive bonding applications. Furthermore, they are ideal for applying thermally conductive pastes. Our piston dispensers operate on the volumetric dispensing principle, with the dispensed material quantity precisely determined by the cylinders' geometry and stroke. This mechanical precision ensures independence from temperature, feed pressure, or material viscosity. When employing 2C media, the mixing ratio remains constant from 1:1 to 100:10 by simultaneously discharging both cylinders into the mixing tube, ensuring perfect consistency.
