Van phân phối keo UV Model 775

The Model 775 is a pneumatically operated spool valve that is designed to accurately dispense a variety of low, medium and high viscosity fluids. This products superior accuracy comes from two main features, its suck-back control, and adjustable flow control. The suck-back feature greatly increases accuracy and repeatability when dispensing materials. Having control over the amount of suck-back assures consistent, stringless dispensing of tackier materials, and prevents droplets from remaining on the dispense nozzle when using lower viscosity materials. The valves other key feature, adjustable flow control, gives users the ability to have complete control over the amount of material dispensed. This product can dispense volumes as little as 0.01 mL and as large as 50 mL.
