1. Introduction
The new series of pilot operated proportional direc-
tional valves D*1FB*EE comes in 4 sizes:
D31FB*EE – NG10 (CETOP 05)
D41FB*EE – NG16 (CETOP 07)
D91FB*EE – NG25 (CETOP 08)
D111FB*EE – NG32 (CETOP 10)
The D*1FB*EE series with explosion proof so-
lenoids is based on the standard D*1FB series.
The specific solenoid design allows the usage in
hazardous environments.
The explosion proof class is
Ex e mb IIC T4 Gb
for use in zone 1 and 2 (conform to ATEX).
Additionally the solenoids are IECEx compliant.
The parameters can be saved, changed and dupli-
cated in combination with the digital power ampli-
fier PWD00A-400 (to be used in an explosion proof
cabinet or outside of the hazardous area).
The valve parameters can be edited with the com-
mon ProPxD software.
Features
• Progressive flow characteristics for sensitive
adjustment of flow rate
• High flow capacity
• Optional: coil to permit ambient temperature up
to +60 °C, modification XG371
