Product Description

Product Description

Plunger Valve (Needle Dispensing Valve)

    The plunger valve, often revered as a needle dispensing valve, is meticulously engineered for the precise and repeatable dispensing of low- to medium-viscosity fluids. Its operation hinges on a vertically moving plunger that expertly opens and closes the fluid path, delivering unrivaled control over shot size. This ensures a sharp, clean cut-off that effectively eliminates any potential for drips.

    With its rapid response time and exceptional dispensing accuracy, the plunger valve has become an industry staple across applications such as SMT assembly, microelectronics, medical devices, and general adhesive dispensing. It is particularly proficient in handling UV adhesives, cyanoacrylates, solvents, oils, and various other fast-curing or low-viscosity materials.

    Offered in both pneumatic and solenoid-driven configurations, plunger valves cater to both manual and fully automated systems. With adjustable stroke and interchangeable needle/nozzle sizes, they provide versatile adaptation to a broad array of process requirements.

Key Features:

 - Fast open/close action for high-speed dispensing, ensuring efficiency.

 - Clean shut-off with superior anti-drip performance.

 - Versatility with compatibility across various low-viscosity materials.

 - Compact design, ideal for seamless integration into robotic or benchtop systems.

 - Optional heating and vacuum assist for tackling challenging applications with ease.

Advantages:
1. Swift and straightforward maintenance procedures guarantee minimal downtime, thus maximizing operational efficiency.
2. Exceptional longevity paired with cost-effectiveness, offering remarkable value over time.
3. Dramatically reduced servicing costs, significantly boosting overall profitability.
4. Optional enhancements such as valve monitoring, mixing tube heating, and dispenser heating for customized performance enhancement.
5. The system is distinguished by its unmatched flexibility, readily adaptable to any specific requirements.

    In a bid to elevate production capabilities, we have ingeniously crafted 2 and 4 needles modules. These modules are impeccably suited for simple dispensing and compact products, maintaining precision while enabling the simultaneous completion of multiple products, thereby enhancing both productivity and efficiency.

Specification

Volumetric piston dispensers epitomize versatility, adeptly managing both ultra-liquid and highly viscous materials. They excel in the application of filled and/or abrasive media and in the deployment of 1K and 2K casting resins, making them indispensable for filling, sealing, and adhesive bonding applications. Furthermore, they are ideally suited for the application of thermally conductive pastes. Our piston dispensers operate on the volumetric dispensing principle, with the dispensed material quantity precisely dictated by the geometry and stroke of the associated cylinders. This mechanical precision ensures independence from temperature, feed pressure, or material viscosity. When employing 2C media, the mixing ratio remains consistently within a range of 1:1 to 100:10, achieved by the simultaneous discharge of both cylinders into the shared mixing tube, ensuring flawless consistency.
