Representing Parker's extensive experience in industrial hydraulics, the pilot operated proportional DC valves series D*1FB is universally applicable and feature progressive flow characteristics for sensitive flow rate adjustment. The standard performance valves have proven very successful in numerous applications all over the world. Series D*1FB is characterized by a solid design which ensures a long lifetime. It offers an excellent price-performance ratio and best conditions for an economic, reliable operation.
The pilot operated proportional directional control valves D*1FB are available in 4 sizes:
D31FB - NG10 (CETOP 05)
D41FB - NG16 (CETOP 07)
D91FB - NG25 (CETOP 08)
D111FB - NG32 (CETOP 10)
Series D*1FB*EE explosion proof
The D*1FB*EE with explosion proof solenoids is the ATEX certified version of the standard D*1FB series and equipped with IECEx compliant solenoids. It allows the usage in hazardous environments. The parameters can be saved, changed and duplicated in combination with the digital power amplifier PWD00A-400 (to be used in an explosion-proof cabinet or outside the hazardous area).

Technical specifications
The pilot operated proportional directional control valves series D*1FB work with barometric feedback of the main stage to the pressure reducing pilot valve. The pilot control pressure of 25 bar allows high flow rates at maximum stability.
The valve parameters can be saved, changed and duplicated in combination with the digital power amplifier PWD00A-400. The valve parameters can be edited with the common ProPxD software.
The innovative integrated regenerative function into the A-line (optional) allows energy saving circuits for differential cylinders. The hybrid version can be switched between regenerative mode and standard mode at any time.
