NORDSON EFD: Valve Controller
This company, a Nordson company, now offers the ValveMate™ 9000, a state-of-the-art precision valve controller. Intricate microprocessor circuitry reportedly ensures the dispensing of precise, accurate, and repeatable amounts of adhesives, lubricants, and other assembly fluids.
The equipment can offer independent dual-valve control programming, each with 24-watt temperature controllers for J-type thermocouples. Each channel can drive a remote high-speed solenoid valve up to 500 Hz. At such fast dispense speeds, the high voltage can potentially damage the dispense system, so the ValveMate 9000 reportedly incorporates a solution with a unique spike-and-hold functionality. When properly set, the spike-and-hold function can allow the controller to spike the voltage for a user-specified spike time and then throttle the voltage down to a user-specified hold voltage after the spike time expires.
