Parker Hannifin has launched the DFplus Generation IV proportional valves. A new dual core processor enables the Generation IV valves to run at maximum performance level and communicate with the PLC simultaneously. The retention of the analogue command signal, in combination with the use of the valve's IO-Link connection for communication, is unique. An integrated near-field communication chip allows users to obtain all status information in the field. A 360° LED at the top of the electronics box ensures that the basic status data is immediately visible. The new electronics are complemented by the mechanical characteristics of the DFplus valves, which can also serve as a 1:1 replacement for DFplus Generation III valves in existing applications.
