Characteristics
The proportional pressure relief valve series RE*E*W
consists of a proportional pilot stage and a slip-in cart-
ridge main stage. A mechanical maximum pressure stage
is optionally available. For sizes NG25, NG32 and NG40
a screw-in cartridge is used, for sizes NG50 and NG63
an additional sandwich unit.
The RE*W model code embraces the pilot valves, covers
and cartridges that are also oered as separate items.
See combination examples for details.
In combination with the digital power amplifier PC-
D00A-400 the valve parameters can be saved, changed
and duplicated.
Features
• Pilot operated with proportional solenoid
• Continuous adjustment by proportional solenoid
• Optional mechanical max. pressure stage
• Cavity and mounting pattern according to ISO 7368
• 4 pressure stages
• 6 sizes, NG16 to NG63
Note
Port X only usable for remote control.
