COMPANY HEADER
The Dymax® Model 485 pneumatic, normally closed needle valve is designed to deliver precise dots or very fine beads of low- to high-viscosity fluids. The valve’s stroke adjustment allows for fine-tuning of the dispense volume, ensuring precise and consistent deposits. Air pressure through the valve retracts the needle assembly from the seat allowing fluid to flow from the valve fluid inlet to the dispensing tip. When the air pressure is eliminated, the spring returns the needle back to its position, closing the fluid path and ending the dispense cycle. The Model 485 is ideally suited for a wide range of applications including glob-top dispensing and dispensing UV light-curable adhesives in medical-device manufacturing.

The Model 485 needle valve is available by itself for mounting into automated systems or is also available in a bench-top configuration, paired with the Dymax® DVC-345 bench-top valve controller and a material reservoir (various styles and sizes available).

Handheld & Mountable Dispensing Systems
Easy to operate, ergonomic designs for handheld dispensing

Dymax® offers handheld and mountable dispensing systems for manual or automated dispensing processes. Our dispensing systems are available with disposable fluid path, diaphragm, needle, and spool valves.

Disposable Fluid Path Valves - Contaminate-Free Dispensing
Dymax® disposable fluid path valves are uniquely engineered to prevent material contamination. The disposable fluid path carries materials from the material reservoir to the dispense tip, sealing fluids in the fluid path. This prevents the fluid from coming in contact with the valve's inner components and ensures a contaminate-free dispensing process. The fluid path is easy to replace and requires minimal clean-up, allowing for rapid material changeover.

Diaphragm Valves - No Fluid Contamination with Less Maintenance
Diaphragm valves are ideal for dispensing light-curable materials, solvent-based products, and reactive materials like cyanoacrylates and anaerobics because the internal design of the valve prevents fluid from coming in contact with the valve's actuating components. This drastically minimizes valve maintenance and production down-time.

Needle Valves - Extreme Precision Dispensing
Needle valves are designed to deliver precise dots or very fine beads of low- to medium-viscosity fluids. Dymax® needle valves feature a stroke adjustment which allows for fine-tuning of the dispense volume and ensures precise and consistent deposits. Handheld and mountable models are available.

Spool Valves - Accuracy with Suck-Back Control
Spool valves are ideal for automated dispensing systems and are designed to accurately dispense a variety of medium- to high-viscosity fluids. The valves' accuracy comes from two main features: suck-back control and adjustable flow control. The suck-back feature assures consistent, stingless dispensing of tackier materials and prevents droplets from remaining on the dispense nozzle when using lower viscosity materials.
Note N/A All systems include a Model 485 valve, DVC-345 controller, selected reservoir, fluid line kits, valve mounting assembly, air precision regulator, airline kits, air filter/regulator, and tip kit
