Set-up:
The valve basically consists of:
Functional description
With de-energized solenoids (5 and 6), the control spool (2) is brought into the central position by compression springs (3 and 4) between the spring plates (8 and 9) (with V control spool without spring plate). With V control spools, the mechanical zero position does not correspond to the hydraulic one.
Functions:
The integrated digital electronics enables the following error detection:
The following additional functions are available:
WIN-PED PC program (version 6 or higher):
To implement the project planning task and to parameterize the IFB-P valves, the user may use the WIN-PED commissioning software.
System requirements
Notice
The "WIN-PED" PC program is not included in the scope of delivery. It is available for free download!
Important notice:
The PG fitting (13) must not be opened. Mechanical adjustment of the adjustment nut located below is prohibited and damages the valve!
