July 8, 2014 - Nordson EFD introduces the 7160RA ValveMate controller for its 782RA internal Radial Spray Valve and 7860C-RS Radial Spinner System. The controller's microprocessor circuitry provides exact time control of the dispense cycle. The ValveMate 7160RA controller is a fast, convenient way to make on-the-fly adjustments for Radial Spray or Radial Spinner system applications. Spray or dispense valve open time can be adjusted in increments as small as 0.001 seconds.
For Radial Spray installations only, an air pressure regulator provides low-volume, low-pressure (LVLP) air to the nozzle, providing a high transfer efficiency without overspray. The result is an exceptional spray pattern definition without time-consuming programming or mechanical adjustments that could shut down the production line. Nordson EFD's 782RA Radial Spray valve is a precision spray valve that produces a narrow radial output ideal 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 paired with the ValveMate 7160RA's built-in air pressure regulator, specially atomized nozzle air ensures high transfer efficiency without overspray.
Instant fluid cutoff at the end of the spray cycle ensures that coatings are applied evenly from start-up to shutdown. Similarly, Radial Spinner Systems apply 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 controlled by the ValveMate 7160RA, the process combines precision with convenience to facilitate 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, Nordson EFD global product line manager. "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."
