Max pressure: 315 bar
Max flow: 125L/min(size 10) 300L/min(size 16)
Pilot operated valve for reducing a pressure (P to A) and limiting (A to T) a system pressure
Actuation by proportional solenoid
Maximum pressure relief function, optional
Valve and control electronics from a single source
Control electronics for type 3DRE(M):
- Analogue amplifier type VT-VSPA1(K)-1in Euro-card format
- Digital amplifier type VT-VSPD-1 in Euro-card format
- Analogue amplifier type VT 11131 of modular design
Linear command value/pressure characteristic curve
Integrated electronics (OBE) with type 3DRE(M)E:
- Low manufacturing tolerance of the command value/pressure characteristic curve
- Ramp times can be adjusted separately for pressure build-up
