A controller, claimed to make the production process more efficient, has been introduced by Nordson EFD. The 7160RA ValveMate provides a way to program Nordson's 782RA internal Radial Spray Valve and 7860C-RS Radial Spinner System. The controller's microprocessor circuitry provides exact time control of the dispense cycle with an improved user interface.
The Radial Spray Valve is a precision spray valve that produces a narrow radial output suitable for coating the interiors of cylinders using a rotating air cap. LVLP technology enables uniform coatings of lubricants, primers, and other low- to medium-viscosity fluids. When used with the ValveMate's built-in air pressure regulator, specially atomised nozzle air ensures high transfer efficiency without overspray. Instant fluid cut-off at the end of the spray cycle ensures that coatings are applied evenly from start-up to shutdown.
Similarly, the Radial Spinner System applies consistent bands of low to medium viscosity fluids, such as lubricants, solvents, and silicone oils. During operation, the system dispenses a controlled amount of fluid onto a spinning disk. As the fluid leaves the edge of the disk, it is evenly distributed onto the production part. When used with the ValveMate 7160RA, the process is facilitated by radial dispensing applications.
"The valves used for dispensing are very important, but it is the controller that actually drives the consistency and reliability of the dispensing process," said Claude Bergeron, Global Product Line Manager, Nordson EFD. "ValveMate controllers provide the primary control of the deposit size. They bring fluid dispensing control close to the dispense valve and provide numerous user-friendly features that simplify valve set-up and operation, maximizing automated assembly machine efficiency and convenience."
