Product Description

Product Description

Plunger Dispensing Valve

    The sophisticated plunger dispensing valve is engineered as a plunger-type dispensing head, meticulously controlling adhesive output through the precise movement of the plunger. It features an innovative back-suction function, ensuring seamless, continuous dispensing. This valve is the quintessential choice for rapid dispensing of high-viscosity and high-liquid materials, including coating fillers, grinding media, and both single-component and two-component casting resins. Its versatility shines with a viscosity range from 10,000 to 100,000, making it indispensable for demanding industrial applications.
    Harnessing the power of the volumetric dispensing principle, the plunger dispensing valve offers unparalleled precision. The dispensing volume is dictated by the cylinder's geometry and stroke, rendering it unaffected by temperature fluctuations, feed pressure variations, or material viscosity changes. The valve guarantees a stable mixing ratio for two-component media, with a broad applicable ratio range from 1:1 to 10:1, ensuring consistent and reliable performance in all conditions.

Advantages:
1. Fast and effortless maintenance, minimizing downtime
2. Extended service life, offering exceptional cost efficiency
3. Dramatically reduced servicing costs, optimizing operational budgets
4. Customizable features including valve monitoring, mixing tube heating, and dispenser heating to cater to diverse needs
5. The system's inherent flexibility allows it to be seamlessly adapted to any requirement, enhancing versatility

To elevate production efficiency, we have ingeniously designed 2 and 4 needles modules, perfect for straightforward dispensing and small product applications. This innovation not only maintains precision but also enables the completion of more products in a single operation.

Specification

    Volumetric piston dispensers are the gold standard for handling both very liquid and highly viscous materials with ease. They excel in applying filled and/or abrasive media, as well as 1K and 2K casting resins, making them indispensable for filling, sealing, adhesive bonding, and applying thermally conductive pastes. Our piston dispensers operate on the volumetric dispensing principle, where the material quantity is precisely determined by the geometry and stroke of the cylinders. This mechanical determination ensures independence from temperature, feed pressure, or material viscosity. For 2C media, the mixing ratio remains consistent within a range of 1:1 to 100:10, thanks to the simultaneous discharge of both cylinders into the unified mixing tube, guaranteeing accuracy and reliability in every application.
