Direct Operated Proportional Directional Control Valve – Series D1FC / D3FC

The direct operated proportional DC valves series D1FC (NG06/ CETOP 03) and D3FC (NG10/CETOP 05) with digital onboard electronics and position feedback provides optimized process speed with high dynamics and flow for various applications. The LVDT is completely integrated into the compact housing,  therefore it does not require an exposed cable connection. Thus an unintended disconnection is impossible. The digital onboard electronics is situated in a robust metal housing, which allows the usage under rough environmental conditions. The nominal values are factory set. The cable connection to a serial RS232 interface is available as accessory.

Optionally available with EtherCAT® interface
The D1FC and D3FC with EtherCAT® interface  fulfill the requirements  of  modern communication between valve and main control. Due to high data transmission speed and short cycle times, also demanding control functions can be realized within the fieldbus system.

The valve is actuated and monitored by the EtherCAT® interface. Actual value (spool position), temperature, operating hours and different error messages are available as diagnostic signals. The valve parameters are factory set  and can be adapted with the Parker ProPxD software via the parametrizing interface.

In addition to the fieldbus communication, the valves provide the range of functions of the standard version including  analogue  command  signal  and  diagnostic  spare stroke. Thus they can be operated independent of the fieldbus control, particularly during commissioning and maintenance.
