H-908A Fine Atomization Valve with Extended Nozzle
The H-908A is a specialized version of our popular H-908 fine atomization valve, featuring an extended nozzle 25mm longer than the standard model. This design enables the valve to reach coating areas around components up to 50mm tall—ideal for boards with tall connectors, electrolytic capacitors, or other high-profile parts.
Advanced Valve Technology
Like the H-908, this is a liquid-gas hybrid spray valve with a bidirectional pneumatic mechanism for precise control. Internal flow distribution and guidance structures ensure consistent spray patterns, while the specialized fluid sealing design extends service life and reduces maintenance frequency.
Performance Specifications
- Coating thickness range: 5-200 µm
- Adjustable coating width: 4-12mm via 7mm nozzle
- Splash accuracy: ±1mm (material-dependent)
- Viscosity range: 50-1000 CPS
- Material compatibility: Acrylic, silicone, UV adhesive, and various liquid coatings
