Safety Warning

Full Product Description

The direct operated valves D1FB (NG06) and D3FB (NG10) are universally applicable, provide high repeatability and low hysteresis for an improved process accuracy.

D1FB and D3FB represent Parker's experience in proportional DC valve technology. They are sutiable for use in applications which require a speed control. Both can be ordered with spool/sleeve design (D*FB*0) for maximum precision as well as spool/body design (D*FB*3) for high nominal flow. The parameters can be saved, changed and duplicated in combination with the digital power amplifier PWD00A-400.

The D1FB*EE series with explosion proof solenoids is based on the standard D1FB series. The specific solenoid design allows the usage in hazardous environments. The explosion proof class is Ex e mb II T4 Gb for use in zone 1 and 2 (conform to ATEX). Additionally the solenoids have IECEx conformity.

Markets:
ā€¢ Industrial
ā€¢ Machine tools
ā€¢ Rubber & tire processing

Features/Benefits:
ā€¢ Spool/sleeve and spool/body design - provides versatile applications, for maximum precision or high nominal flow
ā€¢ Manual override - allows to actuate the valve without current
ā€¢ Low hysteresis - ensures high repeatability and thus improved process and product accuracy
ā€¢ High level of dynamics and flows - optimized process speed
ā€¢ Short delivery time - no storage necessary
ā€¢ D1FB*EE only: optional coil to permit ambient temperature up to +60 Ā°C, modification XG371

Applications:
ā€¢ Suitable for various hydraulic applications
ā€¢ Machine tool
ā€¢ Tire presses
