Product Description

Product Description

Plunger Dispensing Valve:

    The Plunger Dispensing Valve: This advanced plunger-type dispensing head is engineered to masterfully control adhesive output through precise plunger movements. Featuring an innovative back-suction function, it ensures seamless and continuous dispensing. It's the ultimate solution for the rapid application of high-viscosity and high-liquid materials, including coating fillers, grinding media, and both single and two-component casting resins, perfectly accommodating viscosities ranging from 10,000 to 100,000.
    Engineered for Excellence: The plunger dispensing valve operates on a sophisticated volumetric dispensing principle. The volume dispensed is accurately governed by the cylinder's geometry and the plunger's stroke, ensuring consistent performance irrespective of temperature, feed pressure, or material viscosity. It guarantees a stable mixing ratio for two-component media, expertly covering a comprehensive ratio spectrum from 1:1 to 10:1.

Advantages:
1. Effortless Maintenance: Quick and simple upkeep ensures minimal downtime.
2. Longevity and Cost-Efficiency: Designed for a long service life, offering unparalleled value.
3. Cost Savings: Substantially lower servicing costs enhance your bottom line.
4. Customizable Options: Choose from features like valve monitoring, mixing tube heating, and dispenser heating to meet specific needs.
5. Adaptive System: Versatile design adapts effortlessly to any requirement, enhancing operational flexibility.

Innovative Needle Modules: To boost production efficiency, we've engineered 2 and 4 needle modules ideal for precise dispensing on smaller products, maintaining precision while increasing output per cycle.

Specification

    Versatile Volumetric Piston Dispensers: Perfect for both liquid and highly viscous materials, our dispensers effortlessly handle filled or abrasive media, and 1K and 2K casting resins. These dispensers are indispensable for tasks such as filling, sealing, adhesive bonding, and applying thermally conductive pastes. Operating on a volumetric dispensing principle, the material quantity is precisely controlled by cylinder geometry and stroke, unaffected by external conditions like temperature or pressure. For 2C media, a stable mixing ratio is consistently maintained, expertly managing ratios from 1:1 to 100:10 by synchronously discharging into a shared mixing tube.
