Dispensing Valves
What are Dispensing Valves?
Dispensing valves are precision dispensing devices for automated and reproducible application of adhesives and other liquids. These systems enable exact control of dispensing quantities, speeds, and positions for industrial manufacturing processes.
Properties of Dispensing Valves
- High-precision dispensing from microliters to several milliliters
- Reproducible results through digital control
- Various valve types for different viscosities
- Integration into automated production lines
- Fast switching times for high cycle rates
- Easy cleaning and maintenance
Valve Types
- Needle valves: For low-viscosity materials and precise droplet formation
- Diaphragm valves: Gentle dispensing of shear-sensitive materials
- Piston valves: For high-viscosity adhesives and pastes
- Piezo valves: Highest precision for smallest dispensing quantities
Applications
- Die Attach: Precise adhesive application in semiconductor manufacturing
- Electronics manufacturing: SMD adhesive application and underfill
- Automotive Potting Compound: Automated potting applications
- Medical technology: Sterile and precise dispensing
Control Parameters
- Dispensing time: Exact time control for reproducible quantities
- Pressure: Adaptation to various material viscosities
- Flash-off time: Controlled waiting times between dispensing and processing
- Temperature control: For temperature-sensitive materials
Material Compatibility
- 1-Component Adhesives: Simple integration without mixing systems
- Dual Cartridges: Special valves for 2K systems
- UV-curing systems: Light-tight material paths
- High-temperature materials: Heated valve systems
