The Model 300 dispensing system’s diaphragm valve is compact and lightweight, making it easy and comfortable to handle. Accurate, repeatable dispensing can be achieved by utilizing the valve’s material flow adjustment to control the shot volume. The internal diaphragm design of the valve prevents fluid from contacting the actuating components within the valve, reducing damage and wear, while extending the life of the valve. The valve’s design also makes it ideal for dispensing light-curable materials, solvent-based products, and reactive materials like cyanoacrylates and anaerobics.
