Characteristics / Ordering Code
The proportional pressure relief valves series RE*E*T
with onboard electronics and a slip-in cartridge main
stage is electronically based on the functionality of the
digital amplier PCD00.
The digital onboard electronics is situated in a robust
metal housing and can be used in rough environments.
The nominal values of the valves are factory set. Addi-
tionally the ProPxD software permits the editing of all
parameters. The software is also used for the digital
electronic modules. The cable for connection to a serial
RS232C interface is available as accessory.
The valves are optionally available with a mechanical
maximum pressure adjustment.
The RE*E*T model code embraces the pilot valves, covers
and cartridges that are also oered as separate items.
Features
• Pilot operated pressure relief valve
• Onboard electronics
• Optional mechanical max. pressure stage
• Factory setting
• Ramp time adjustment
• Linearized characteristics
• 4 pressure stages
• Cavity and mounting pattern according to ISO 7368
• 6 sizes, NG16 to NG63

Interface Program
ProPxD interface program
The ProPxD software permits comfortable parameter
setting for the module electronics. Via the clearly arranged
entry mask the parameters can be noticed and modied.
Storage of complete parameter sets is possible as well
as printout or record as a text le for further documenta-
tion. Stored parameter sets may be loaded anytime and
transmitted to other valves. Inside the electronics a non-
volatile memory stores the data with the option for recal-
ling or modication.
The PC software can be downloaded free of charge at
www.parker.com/isde – see page “Support“ or directly at
www.parker.com/propxd.
Features
• Comfortable editing of all parameters
• Depiction and documentation of parameter sets
• Storage and loading of optimized parameter adjust-
ments
• Executable with all actual Windows
®
operating
systems from Windows
®
XP upwards
• Plain communication between PC and electronics
via serial interface RS232C
The parametrizing cable may be ordered under
item no. 40982923.
