Variable-speed pressure and flow control system Sytronix DFEn 5000 SYHDFEn-1X
-
Version With axial piston variable displacement pump A4VSO
-
Size 125 … 355
-
Component series 1X
-
Maximum operating pressure 350 bar
-
A SYHDFEn-1X control system is used for the electro-hydraulic control of swivel angle, pressure and power (partially optional, see ordering code) of an axial piston variable displacement pump.
The control system consists of the following components: - A4VSO axial piston variable displacement pump optimized for the operation in the control system
- VT-DFPn-.2X proportional valve as pilot valve with integrated electronics including inductive position transducer for valve position sensing.
- Position transducer for sensing the swivel angle
- Pressure transducer with suitable signal level and dynamics (separate order)
